The plant aloe vera is one type of houseplant commonly found in most homes. Aloe vera is characterized by its fleshy leave that looks triangular and the color can range from light to dark green. But are you aware that some plants have a good resemblance to aloe vera? Plants that look like aloe vera will be highlighted here in case you’re looking for a substitute for aloe vera.
Other types of plants share some good resemblance with aloe and this characteristic similar appearance includes the leaves and the flowers.
The plant agave is one common example of a plant that looks like aloe vera. It is a stemless plant that is perennial. The leaves of the agave plant look big and fleshy just like aloe plants. Agave plant leaves can be broadened or narrowed to form a dense root rosette. Then the end of the leaves forms a sharp point and most species of agave have bent or straight spines on their edges just like aloe vera. The plant agave usually comes in various colors such as green, gray, or blue-green.
Additionally, agave plant has fibrous roots and this allows them to attach themselves to rocks or trees. So, this allows them to create their support system for growing vertically high above the ground level.
Caring for agave plants is almost the same as caring for aloe plants. So, just like aloe vera, the plant is hardy and can be grown indoors easily.
The maguey plant is another succulent that looks like a cactus plant due to the thorny edges on the foliage. So, most people may think this is a cactus that looks like an aloe vera plant.
This plant is related to agave plants. Maguey plants can grow and attain a height of up to 20 feet depending on their variety. Therefore, this plant may look like a different species altogether. Maguey plant leaves look broad and long just like aloe plants.
Maguey is a good choice for houseplants and a west-facing window suits them because they are a low-light-tolerating plant. This plant also doesn’t need to be watered too much because over-watering can lead to root rot.
3. Haworthia
Another great substitute for the aloe plant is the haworthia plant. The plant is also pretty easy to grow indoors due to their light and water requirements that are easy to meet.
Haworthia shares the same family classification as the aloe vera plant. Similar to aloe plants, the foliage of haworthia grows in a rosette pattern and emerges from the stem axis of the plant. Haworthia plant has foliage with white bands that looks raided on the surface and this is why the haworthia is regarded as a zebra plant.
Gasteria is a type of succulent with fleshy leaves that are arranged in a rosette form. The foliage of gasteria is long and they have this rough texture. They may also possess some colors and markings depending on the species.
The succulent of gasteria grows up to twelve inches or more and it has green-gray leaves with a tiny bit of orange hue. The flowers of gasteria can range from pink to yellow and they usually bloom during the fall months. The blooms gasteria produces are almost the same as that of aloe vera and haworthia. So, these are similar-looking plants suitable to be grown indoors.
Also, gasteria succulents are less sensitive to climate conditions. Hence, the plant can’t tolerate extreme temperatures and they don’t demand too much water like aloe would.
5. Yucca
Another plant that looks like aloe vera is yucca and they are related to agaves. But there is a bit of a difference in the leaves and shapes. The plant yucca also has this rosette foliage form that is sword-shaped and known to be tough. Yucca has this whitish bloom that grows at the upper part of its stem in big terminal panicles.
6. Snake plant
Snake plant is one popular houseplant that looks a bit like aloe vera. The plant is characterized by dark green, lance-shaped leaves that form a dense rosette pattern when grown in a pot or container.
Snake plants can attain a height of about 4 feet and this depends on how the plant is bred. Also, the darker stripes and borders on the leaves can differ greatly.
7. Young pineapple plant
Before the plant pineapple bears fruit, the young plant pineapple can easily be confused with the aloe vera plant. The foliage of young pineapple resembles the ones seen on aloe vera leaves, and also just like in gasteria plant leaves or yucca leaves.
Similar to other plants listed above, their leaves are in a rosette pattern with sharp spines along the edges to protect the plant as well as the fruit.
Unlike the lengthy oval-shaped leaves of most succulent plants, the young pineapple leaves tend to be more rounded. They also have these pointed tips rather than straight ends as you would find on most other plants you will find in this family classification.
Aloe Type Succulents
When it comes to types of aloe plants, there are actually over 500 species! But I thought I’d share some facts about some of my top 10 choices when it comes to aloe succulents. Let’s take a closer look.
Aloe Broomii. You’ll see this type of plant often as it’s a very common ornamental plant. They work best outdoors in a gravel or rock-type environment. They have light green leaves and wildlife such as birds will enjoy this plant.
Aloe Crosby’s Prolific. This is essentially a mini aloe. It usually has orange or red flowers and is ideal for a flower bed.
Aloe Ferox. You may know this succulent better than cape aloe. This plant contains the gel you’ll so often see in products such as after-sun and skincare. It’ll be brown and have orange flowers.
Aloe Cameronii. In fall, it turns a deep red color, which is why it’s so well-loved. You may know it better than red aloe.
Aloe Barbadensis Miller. Another common type is the Barbadensis Miller. It has yellow flowers and contains the gel that soothes products such as after-sun. This is known to help wounds such as burns heal more quickly.
Aloe Petricola. You may know this type of aloe better than stone aloe. It’s grown from the winter but usually peaks in the summer months. It requires little attention and can grow in many environments. It’s bright in color, which is the main attraction of this plant.
Aloe marlothii. This plant can grow up to 5 feet tall. The leaves are usually a dark red color, whereas the flowers are much lighter, such as red or orange.
Aloe Hereroensis. You may know this plant better than sand aloe. This plant is ideal to use in flower beds. It has red flowers, but dark red spines.
Aloe Rubroviolacea. This plant is known better as Arabian aloe. It gets its name because it’s such a hardy plant and can do well in dry conditions. You can use this plant in many places, such as flower beds and gardens. This type of aloe can last throughout the year and will change color depending on the season.
Aloe ciliaris. An ideal houseplant, but can also be kept outside too. One of the main perks of this plant is that it can grow quickly. It blooms during cooler months and has orange flowers.
Aloe Vera Plant vs Agave
While the aloe vera plant and the agave plant look very similar, there are actually a few differences between the two; and they are definitely not the same. One of the main differences is size. Aloe is usually much smaller than agave. As well as this, aloe leaves contain the beneficial gel we use for skincare products, whereas the agave plant doesn’t.
Conclusion: Plants That Look Like Aloe Vera
Plants that look like aloe vera are nice for substitution. However, you may not get the medicinal or beneficial use aloe vera plant provides. But you can still get some similar growing conditions as aloe plants.
Do you know of any other plants that look like aloe vera? If so, please feel free to let me know in the comments below. And remember, sharing is caring!
FAQs
Is my plant Agave or aloe?
Even though agave and aloe look similar, you can still determine if your plant is agave or aloe by looking at the differences. Agave is characterized to have bigger and spinier leaves compared to aloe. Agave plants have their spines to be very sharp whereas aloe plant spines are often soft to feel.
Is Agave the same as aloe?
Agave and aloe plants may look quite similar, but there are some differences between them. For instance, agave is usually bigger and possesses sharp spines on their leaves. Then aloe vera leaves on the other hand are serrated but not so sharp.
What plant looks like aloe vera but isn’t?
There are several plants that look like aloe vera but they are actually not aloe. Some of these plants include maguey, agave, yucca, haworthia, gasteria succulent, and young pineapple plant.
Is Yucca an aloe plant?
Yucca is often mistaken to be an aloe plant but it isn’t an aloe plant. Yucca plants have this leaf texture with some smooth edge on each side so this gives yucca plants a similar look to those found on the base of the leaves of aloe plants.

When starting out growing various plants indoors, different questions may pop into your mind. Questions such as “how many plants can I grow per 1000 watt light?”.
Every grower wants to maximize their yield after all the hard work they put into their indoor garden. Providing your indoor plants with light is very essential for their development. High-pressure sodium (HPS) lights have been in existence for almost 50 years, and are some of the most widely used grow lights. They have been providing light energy for indoor plants growing needs.
Now, you must get the right plant coverage for the particular bulb wattage you have. This is why we are going to be looking at how many plants you can grow per 1000 watt light. We will also be looking at other grow light plant coverage for 1000w. So, read on to find out.
How Many Plants for an a1000-Wattt HPS?
The light wattage will decide how much area or the coverage area you can light up. So, for how many plants for a 1000 watt HPS bulb? The answer should be around 5 by 5-foot or 25 square feet.
Even though everyone has their methods, it all boils down to what method works for you. Some growers have boasted of growing about 6 to 9 plants using 1000-watt HPS. Some even grow smaller plants while using the SCROG and SOG techniques to manage space.
How Many Plants per 1000 Watt Light?
Various grow lights will have a coverage capacity depending on their wattage. Let’s take a look at some 1000-watt to grow lights and their plants’ coverage capacity:
· 1000 watt LED grow light plant coverage capacity
A 1000-watt LED grows light plant coverage capacity will also be around 5 by 5 feet or 25 square feet area. You should also take note of the quality of the LED to-grow light you’re using as some lights are more efficient than others. Different brands will offer different benefits to your plants.
Another important thing to understand is what is actually meant by a 1000-watt LED. The meaning of a 1000-watt LED is referred to as the equivalent of a 1000-watt HID light. The only difference is that this LED light consumes less than 1000 watts of light.
We have what we call LED actual wattage and labeled wattage. The labeled wattage of the LED growth light is written in bold words by the manufacturer. The actual wattage is the actual amount of power the LED light draws and it’s not usually up to the labeled value.
For instance, a 1000-watt LED grows light actually wattage maybe around 500 to 700 watts but will give you an output that almost equals a 1000-watt HID. You can find the actual LED wattage value if you dig through the manufacturer’s manual.
Thus, this shows that LED grgrowthights are more efficient by offering you more benefits while saving you power consumption. So, the coverage area of LED actual wattage of 500 to 700 will also be a 5 by 5-foot area.
· 1000 watts for other HID grow light plant coverage
We have looked at how many plants for a 1000 watt HPS will be. So, let’s discuss other 1000 watt HID bulb plant coverage (such as CMH and MH).
The difference between HID light coverage and LED light coverage is not so much. 1000 HID watt coverage offers roughly a close range of coverage area the only difference is the HID reflector used.
Umbrella reflectors for instance will offer you a big light coverage area. However, the light intensity will not be so great. Other focused reflectors such as a hood will offer you a smaller coverage area with more light intensity.
Taking a look at the types of HID bulbs we have, here is their plant coverage capacity:
Ceramic Metal Halide (CMH): even though 1000-watt CMH bulbs may be scarce (the common watt seen is 315w), the ones that are actually 1000 watts will have plant coverage of about 5 by 5 feet area.
Metal Halide (MH): for a metal halide bulb, the plant coverage is about 7 by 7 area feet for vegetative growth. While for the flowering phase, the coverage area is about 5 by 5 feet. However, we recommend not using a metal halide bulb for the flowering phase. You should rather use HPS grow light if you want big buds and yields.
How Many Plants per Light: Factors to Consider
Now, talking generally about the number of plants to be grown per grow light, we would say 1 to 8 plants. Make sure you don’t grow more than this number so you don’t limit your yields.
Following the right number of plants to grow per plant will give your plants a good chance to flourish thereby resulting in good yields. However, if you grow more than 8 plants using a single grow light, your plants won’t receive adequate light and space to grow.
Here are other factors to consider when deciding how many plants to be used using each grow light:
Power of grow light
You should also note that the power of your grow light will also be another determinant of how many plants you can grow using that light.
Condition of grow space
Another factor to consider when deciding how many plants to grow per light is the condition of your grow space. If your grow space already a bit receives natural light, then a not-so-strong grow light will be fine. You can even place your grow light higher to increase the coverage area.
Plant growth stage
The stage your plant is in will also have a determining fafactor inour choice of grow light. Some flowering plants require high light intensity, thus, a 5 by 5 feet coverage area should be ideal for 1000 watt light. On the other hand, vegetative plants such as lettuce can allow you to hang your light higher for larger coverage. You can use a coverage area of 7 by 7 feet for plants in their vegetative stage of growth.
1000 Watt HPS Grow Light Coverage
HPS grow lights are ideal for use in grow tents, large grow rooms, and greenhouses. 1000-watt HPS grow lights are the most powerful grow lights and have a wide coverage area of up to 49 square feet.
A 1000-watt HPS grow will effectively cover a growing area of 36 square feet. The difference between the maximum coverage area and effective coverage area is dependent on the depth and height of the plants you are growing. The denser the plants, the lower the coverage area your grow light will have.
Unlike other grow lights such as LED, HPS grow lights generate heat. So regardless of the growing area you are using the lights on, they must be mounted farther from the plants to avoid burning them.
Depending on the plants you are growing, you can mount an HPS grow light anywhere between 6 to 24 inches from the plant canopy. Make sure you do sufficient research on your plants so that you can create the ideal growing conditions for them and not burn them with grow lights. You will also need to set up an efficient ventilation system to help keep the humidity conditions right.
To even further improve your plant growth potential, you can set up your HPS grow lights with timers and light rails. The timers will help you keep the plants in a consistent light schedule. The lights will turn on and off at the same time every day. Light rails will help you to move the light fixtures along rows to ensure that all the plants get an equal amount of light in the entire growing area.
To get the best efficiency out of HPS grow lights, they should be replaced every 14 months.
LED Equivalent to 1000 Watt HPS
LED lights can be used in place of HPS. Due to the difference in the designs of these lights, however, there will be differences in the wattage replacements of these two lights.
LEDs are designed to have a lower energy consumption compared to HPS. Because of this, LEDs will have a lower wattage.
If you are looking for an LED equivalent to 1000-watt HPS, a 300-Watt LED High Bay is a good choice. Or you can replace a 1000-Watt Metal Halide Shoebox with a 300-Watt LED Shoebox. They can deliver the right amount of light required, last longer, and have reduced energy consumption.
Because of the differences in the equivalencies, it may not be best to base your decision on grow light wattage. Instead, you can use the number of lumens your plants need. Once you understand that, it becomes easy to find a replacement.
1000w DE HPS Distance From Plants
The distance at which you should place the grow light from the plants depends on the strength or intensity of the light. The stronger the light, the further you will need to hang them from the plants.
Because a 1000W DE HPS is quite a strong light, you should hang it at least 15 inches away. And if it is even stronger, place it further away but do not go farther than 30 inches. If you place the lights too far above the plants, they will love vitality.
A 1000w light produces a lot of light so you will need to err on the side of caution with this one. If your plants are starting to burn, you will notice the leaves starting to bleach. Some strains of plants will bleach easier or faster than others. So place your grow lights at an appropriate distance from your canopy to avoid heat stress. If you are using this light in a grow tent or a well-reflective light, you will not have much of a problem with this
Conclusion – How Many Plants Can I Grow per 1000 Watt Light?
Now, we have answered the question “how many plants can I grow per 1000 watt light?”, you should be well on your way to comfortable and confidently purchasing the best grow lights for your plants. Keep all considerations such as the density of the plants, grow light area, the distance between plants and light, and the height of your plants when purchasing a grow light. This way you will be guaranteed to get the best out of your grow lights while avoiding issues such as leaf burn.
So, we hope this post has been able to enlighten you on deciding your plant grow light coverage.
FAQs
How much area does a 1000 Watt HPS cover?
It isn’t set in stone, but the amount that it covers is thought to be around 49 square feet.
The best way to calculate how much area you will be heating with a HPS is by looking at the Watts. The power rating of your HPS (1000W) is divided by the number of hours in a day and the number of days in a year. If you are heating with a HPS for 24 hours a day 365 days a year, the area you are covering is about 1.5 acres.
The more you put distance between the light and the walls and ceiling the less wasted energy you will have.
How many plants can I grow with 1000 Watt HPS?
The answer is that it depends on how much light you are using, how much space you have and what your plants require. For instance, let’s say you have a 10′ x 20′ growing area. If you only use 4″ of light, you can grow about 15 plants.
This means you would need 2 bulbs to cover this area. But if you were to use 8″ of light, you could grow 50+ plants in this space. So, you could easily grow up to 200 plants with 8″ of light and a 1000 watt HPS bulb. Let’s take this one step further. Say you have a 2000 watt HPS, you could grow 500+ plants in this space. So the bottom line is you can grow just as many plants with a 1000 watt HPS as you can with a 2000 watt HPS.
So, it gets a bit tricky. The first thing you need to determine is how much light you will need. The number of plants you can grow will depend on the amount of light you have available.
How far should 1000 Watt HPS be from plants?
You should be at least one meter away. But, if you want to go further, go ahead.
What LED is equivalent to a 1000w HPS?
Black Dog PhytoMAX-2 could be easily considered an equivalent. The only issue is thet they are very expensive, and for this reason very few people go for them.
How much does it cost to run 1000 watt HPS?
You can get a 1000Watt HPS for $0.90/hour. However, you will need to do some research to find the right model and wattage, as well as getting a supply voltage of around 110V. I would recommend finding a manufacturer like Noctua or CLC or XSPC that makes HPS units for your particular requirements and then order online.

Selecting the best Kelvin for growing plants LED for your plants’ growing needs is one essential factor in an indoor garden. As we know, grow lights mimic the light provided by natural sunlight and this must be done in the presence of the correct light temperatures.
Your plants will flourish when they are exposed to the appropriate light temperatures so this is why you must ensure that you get it right. So, if you are wondering how to go about the best light temperature for your growing plants, we’ve got you covered.
We are all about easy indoor gardening. So, by the end of this article, you should have an idea of the right color temperature for each of your plant growth stages and more.
What is a Grow Light Color Temp?
Grow light color temperature is the accurate light spectrum provided by a grow light and is required for each plant growth stage. It is a means of showing the appearance of the light which is supplied by a light bulb. It is essential for a grow light to contain the necessary spectrum so a plant can grow healthily and adequately.
Light is known as electromagnetic energy which is measured in wavelength. This wavelength can be seen in various visible light colors waves that vary from red, blue, and yellow, to green. Blue and red light are the colors mostly absorbed by plants for the photosynthesis process.
The color of light supplied by a particular grow light is known as color temperature and is measured in Kelvin (K). The Kelvin has a scale that ranges from 1,000 (warm or red) to 10,000 (cool or blue).
Kelvin color temperature scale
Grow light Kelvin rating or scale is a measurement of color temperature and it’s used to explain how different light temperature appears. Practically every light that comes with bulbs will be associated with Kelvin color temperature.
The Kelvin scale figures at the lower end offer hues of red. While on the other end, the Kelvin scale where the figure goes higher, it offers hues of blue.
Spectrums with low Kelvin ratings (around 2000K to 3000K) are also described as warm, while those with higher ratings (5000K or higher) are often referred to as cool.
Take, for instance, blue light is essential for vegetative growth. On the other hand, red light is required for the flowering stage and fruit production. Therefore, the color temperature will assist in deciding the best light temperature for your plant’s growing needs.
Plants contain various pigments they use in absorbing or reflecting certain light wavelengths. These pigments are used in the process of photosynthesis whereby plants make use of light energy to produce their food.
So, let’s take a look at two (chlorophyll and carotenoid) of these pigments involved in photosynthesis:
Chlorophyll: the green pigment contained in plants that allows them to manufacture their food is chlorophyll. It is the most abundant pigment found in plants, and chlorophyll A is responsible for the absorption of light energy.
Carotenoid: the second most important pigment is the carotenoid. Carotenoids also help plants take in light energy, which in turn, transfers the energy to chlorophyll.
The Best Grow Light Color Temperature For Growing Plants
Choosing the right color temperature for the various stages of your plants can be determined by the values on the Kelvin scale.
Also, different grow lights are configured in various ways. Some grow lights offer a full spectrum for your plants and will not require you to switch lights for different plant stages. Examples of such grow lights are LED lights.
While some grow lights are not configured to be full spectrum. Thus, you will be required to switch these lights as your plant enters its different growth stages. Examples of such grow lights are traditional lights such as fluorescent, HID, and so on.
Most of the LED grow lights have been we have in the market are configured with full spectrum. Therefore, you can use the same light for all your plant growth stages. The only thing you need to do is position the LED to grow lights distance to your plants’ canopy appropriately as they enter different growth stages.
So, let’s look at the required or best light temperature for your growing plants in their different growth stages:
1. Best kelvin for seedlings and clones
The best color temperature for seedlings and clones is the blue spectrum. If you’re using the traditional grow lights, choose daylight bulbs that fall on the higher end of the Kelvin scale. Use 5,000 and above Kelvin figure bulbs for your seedlings.
We recommend you use fluorescent bulbs for seedlings and clones because they don’t produce too much heat. The clone and seedling stages are the most fragile, and therefore need to be handled with care.
Other traditional lights such as the HID may also be used for your seedlings and clones. However, they produce a lot of heat. So you need to be extremely careful so they don’t burn your fragile plants.
2. Best kelvin for the vegetative stage for rowing plants
The vegetative stage of a plant also requires blue lights which are at the higher end of the Kelvin scale. Just like seedlings and clones, vegetative growth should use bulbs ranging from 5,000 to 7,500 on the Kelvin scale. However, the lighting needs to be more intense for vegetative growth.
3. Flowering and fruiting stage for growing plants
For the flowering and fruiting stage, your plant will require the red light spectrum which is at the lower end of the Kelvin scale. This light spectrum will encourage flowering, blooming, and fruiting.
Use light bulbs that range from 2,000 to 3,000 Kelvin values. HID lights such as high-pressure sodium (HPS) offer more of this red light spectrum. You can also use the LED full light spectrum for all plant stages.
Is Warm Light Good for Plants?
When shopping for grow lights, you will notice that they are labeled with numbers such as 2700K or 4000K. These numbers refer to the relative warmth or coolness of the light on the color spectrum. The higher the number, the cooler the light.
The growth of plant foliage is usually best around 6500k. However, they still need a period of warmer light of around 3000K to produce flowers, and eventually fruit.
So is warm light good for plants? The answer to this question depends on what you ultimately want to produce with your plants. If your goal is to produce seedlings, leafy green vegetables, or root crops, you need higher spectrum bulbs, which are the cooler light colors. But if you want to produce flowers, such as in the case with marijuana, or any other fruiting plants such as cucumbers, tomatoes, peppers, and lemons, you will require warm light which is in the lower spectrum. Warm white light is better and stronger on the red end of the spectrum.
Because lights require different lights for the different growth stages, it might be best if it gets a full spectrum LED, so you will not have to worry about switching lights as your plant progress.
3000K vs 5000K Grow Light
Both the 3000K and 5000K grow lights are in the white light spectrum. The difference is that 3000K is a warm white, whereas 5000K is a cool white.
A 3000K grow light bulb produces a soft white light which can also appear yellowish. One of the best uses for this light is in the bedroom as it gives a relaxing mood. For plants, a 3000K grow light is required for flowering, and thus fruit. 3000K is more efficient for flowering when counting grams per watt.
A 5000K grow light is ideal for plants in the vegetative stage of growth. The big advantage of this grow light is that it will help your plants to produce tighter internodes which will give you a more balanced distribution of light over the colas later.
Plant Light Requirements Chart
Different plants have different light requirements. Light is required by plants to produce chlorophyll for energy through photosynthesis. If they do not receive enough light, they will end up weak and pale. If a plant is overwatered, its roots will not grow enough to absorb the moisture.
To determine how much light your plant is receiving in the environment it is, there is a simple test you can use called the shadow test. This works especially well for indoor plants. Follow these steps to do so:
Get a large, blank piece of paper.
At the brightest time of the day, place the paper vertically and facing the light source, at the precise height and location you would like to place your plant.
Place your hand a few inches away from the paper.
Use the Light Requirement Chart (below) to determine the type of lighting that your plant will be receiving
Conclusion – The Best Kelvin for Growing Plants LED
This article has shown us that light temperatures are essential for plant development. It has also shown that there are suitable Kelvin ranges for the different growth stages that plants go through. It is important to make sure that you stick to the relevant Kelvins at the appropriate growth stage to get the best out of your grow lights and your plants.
Using the right Kelvin for your growing plants will also help you save costs. We hope this information will be of great help to you and your plants on your growing journey.
Happy growing!
FAQs
Is Warm light or cool light better for plants?
In the case of growing houseplants, you should be aiming to use cool light. Cool light comes from a combination of the sun and air conditioning. The sun produces light that is predominantly yellow-orange, with a very slight blue tinge, and the air conditioning adds red and far-red wavelengths.
Cool light is best for plants because it mimics sunlight, which they need to grow. The sun produces both warm light and cool light. Warm light is a combination of both blue and yellow wavelengths. Q: Do you know how to grow indoor plants in winter? A: Yes. You can grow houseplants i
Is 5000 Kelvin good for plants?
Yes, 5000K is enough for most plants. But don’t use 5000K as the maximum. You can get some plants that flower really well under 2000K, such as geraniums and some begonias. There are many other plants that need a higher light spectrum. If you want to grow plants indoors, then your best bet is to set your LED to about 5500K, but not at full power. If you do this, then you can turn the lights off for 4-8 hours at night, which will give you enough light to get by without turning on the lights. Then you’ll have a nice light spectrum in the middle of the day.
Will LED lights help plants grow?
One of the biggest questions that people have about growing plants indoors is whether it’s possible to grow plants in an LED light. The short answer is yes, you can, but there are some things to consider before you make the switch.
It’s not as simple as just putting a plant in an LED light and leaving it there all day, because not all LEDs produce the same amount of light. A lot depends on the type of LED bulb used, the wattage and the number of bulbs used. There’s also the matter of how far away your plants are from the bulbs.
Does regular LED light help plants grow?
These lights have different wavelengths that affect plant growth. Red light stimulates photosynthesis. Blue light promotes cell division. White light is a mixture of red and blue. Now, we can use all three colors together to create the spectrum of light. There are many types of LED lights. The most common type is the LED strip. It has red, blue, and white LEDs. We can also put them in groups. For example, we can use a single red LED on one side of the plant and a single white LED on the other. This will make it easier to grow plants.

The most rewarding advantage you get from making your hydroponics nutrients recipe is that you get to cut down on your expenses. Making your own nutrients can also be a fun thing to do. You would be amazed to know you’ve been buying these commercially made nutrients at high prices when most of the ingredients used are very affordable and easily obtainable.
Now if it interests you to grow plants for a long duration or you’re growing on a large scale, commercial nutrient purchase may not be beneficial to you. Preparing your own formula may be the best way to go. So, if you’re wondering how best to make a DIY hydroponics nutrients recipe, we will guide you into this.
The combination of nutrients and water makes up a hydroponic nutrient solution. Before we look into the nutrient recipe, let us look at the important nutrient elements hydroponic plants require to grow successfully.
Nutrient elements required for making hydroponic nutrients solution
For hydroponic plants to grow adequately, they require both macronutrients and micronutrients present in their nutrient solutions.
Macronutrients
Macronutrients are higher concentrated elements required by plants to grow appropriately. They include magnesium, carbon, calcium, nitrogen, hydrogen, sulfur, oxygen, phosphorous, and potassium.

Nitrogen and sulfur nutrient elements will assist in the production of protein and amino acids for your plant. Potassium and magnesium will produce sugar and starch. While phosphorus is required for plant growth and photosynthesis, and calcium is also required for growth. The production of chlorophyll requires magnesium and nitrogen.
All these elements must be contained in your hydroponic nutrients solution or else it will be rendered futile.
Micronutrients
Plants also need micronutrients or trace elements in small amounts to develop. Ensure they are present in your homemade hydroponics nutrients recipe so your plants can thrive well. Micronutrients required by hydroponic plants are zinc, boron, cobalt, copper, manganese, iron, chlorine, and molybdenum.
Recipe On How to Make Hydroponic Solution at Home
All types of plants flourish with the presence of both macronutrients and micronutrients. However, the concentrations of these nutrients will vary depending on the type of plants and growth stages. They can be in vegetative, flowering, or fruiting stages.
Guidelines for making macronutrients recipe
Obtain the base of your fertilizer. The base includes nutrient elements such as sulfur, calcium, phosphorous, nitrogen, and so on. They usually come in form of salts and they are mixed with water to form a solution.
These are the amounts of salts you should use for your homemade hydroponics nutrient recipe:
4.5 tablespoons of calcium nitrate
4 tablespoons of potassium nitrate
4 tablespoons of magnesium sulfate, calcium carbonate, and magnesium carbonate
10 gallons of water
Instructions:
Ensure you use clean or filtered water.
To your 10 gallons of water, add two tablespoons of salt to each gallon of water.
Ensure you mix or add one tablespoon of salt at a time.
As you mix the solution, the salts will break down their nutrient elements to make them available to your plants.
Guidelines for adding/preparing micronutrients recipe
Instructions:
Using a different container, measure 1 quart of water and add 0.25 tablespoons of boric acid as well as 0.1 tablespoons of manganese chloride. Ensure you stir the mixture adequately.
After mixing, pour half a cup of this mixture and add it into the macronutrient solution.
Now get a different container and add 1 quart of water and mix 0.5 tablespoons of chelated iron.
Then add 3/5 cups of this mixture into the already made macronutrient solutions.
Tips for DIY Organic Hydroponic Nutrients Solution
One of the biggest reasons why people are intimidated by hydroponics is because of the daunting task of having to deal with nutrients. Getting the balance of nutrient balance may seem like a monumental task that can only be done by experts or robots. Store-bought hydroponic nutrients can also be quite pricey. This leaves people wondering if they can be able to sustain nutrient provision to their systems.
There is however a way to avoid all these issues. Here, we are going to show you how you can make your own DIY hydroponic nutrients.
Hydroponics can be organic as well. If you want to have an organic hydroponics system, you can achieve it as long as you refrain from using any chemicals, pesticides, and artificial fertilizers. You can obtain all-natural products from things like manure and plant matter.
The advantage of having an organic system is that you produce better-looking crops, the crops taste and smell better, as well as have better nutritional value.
Some of the most common organic fertilizers that are used for hydroponic nutrients include:
Manure based
Fish meal
Gypsum based
Bone meal
Guano
Blood meal
Compost based
Plant-based
These materials can be mixed and matched depending on the system that you are using and the requirements of the crops that you are growing.
A basic NPK proportion of 15-15-15 is mostly used by many hydroponic gardeners. Many other macronutrients and micronutrients such as calcium, sulfur, copper, boron, zinc, iron, and manganese are also necessary.
While there are all these options available to make hydroponic nutrients, in some cases it might be best to avoid substances like manure because of the risk of bacterial contamination. Another issue with these kinds of substances is that they can cause other problems such as clogging of pipes.
The best organic fertilizer for your hydroponics system ultimately depends on the system and crops you are growing. With that said, there are many possibilities once you get the hang of it.
Once you have decided on the materials you are going to use for your DIY hydroponic nutrient solution, these are the materials you will need to mix everything all together before incorporating it into your hydroponics system:
When making your nutrient solution, it is important to monitor the EC and pH as they are essential to water quality parameters. The pH affects the ability of the plants to absorb essential elements from the nutrient solution. Most plants prefer acidic conditions in the pH range between 5.8 and 6.5, you should ensure that you’re solution stays within this range. Make pH adjustments to your system as necessary during the growth of your plants. You can make use of pH up and down to adjust the pH accordingly.
Simple Hydroponics Nutrients
It is easy to make your own, natural fertilizer for hydroponics as we have demonstrated above. It is also possible to make your formula with readily available components. You can do this by using normal hydroponics fertilizer or making your own.
A simple way to make hydroponic nutrients is to purchase some water-soluble fertilizer. Good ones are 20-20-20 or 24-8-16 (NPK), which are available from nurseries, garden supply stores, and even online stores such as Amazon. When purchasing these commercial nutrients, make sure you get the ones that have micronutrients included.
Add two teaspoons of this fertilizer per gallon of water and mix very well. Add one teaspoon of magnesium sulfate (Epsom salts) per gallon. After mixing these, thoroughly stir the mixture and ensure that everything is well incorporated. And then it is ready for use.
Cheap Hydroponics Nutrients
If you have ever owned a hydroponics system or looking into having and running one, you will know how expensive pre-made hydroponic nutrient mixes are very expensive. If you are running a small system that has not yet reached optimum production, you may find yourself making a loss from having to purchase nutrients.
Here are some cheap hydroponics nutrients for you to try out:
Formula #1
This formula will work for a 5-gallon container of nutrient solution. This solution works best for non-recirculating and small systems, such as DWC and raft systems:
Masterblend Tomato 4-18-38: 10 g
Calcium Nitrate 15.5-0-0: 10 g
Epsom Salt: 5 g
While using this formula, if you notice any deficiencies in your plants, you should use a supplementary formula for extra nutrition.
Formula #2
This nutrient mix needs a few more components but it is a very easy mix. Once mixed, add 10 g of the mixture for each gallon of water in your system:
Potassium nitrate: 255g
Calcium Phosphate: 198g
Magnesium Sulfate: 170g
Powdered Ammonium Sulfate: 43g
Monocalcium Phosphate: 113g
Iron Sulfate: 1/2 teaspoon
This mixture is highly concentrated, so make sure to wear protective clothing to avoid skin and eye irritations.
Formula #3
This 2 ingredient solution is quite cheap and very easy to make:
Seaweed (Kelp): 6oz
Epsom Salts: 5 teaspoons – 1 teaspoon per gallon of water
Wrap your seaweed in cheesecloth and tie it with twine. Add 5 gallons of water into a bucket and add the seaweed bag. Leave this mix outside in the sun for 5 days. Afterward, add 5 teaspoons of Epsom salts. You can either add this entire mixture into your hydroponics tank or in small increments.
DIY Hydroponic Nutrients From Compost
These are the steps to follow if you want to make your own nutrients from compost:
Place a gallon of compost into a 5-gallon bucket
Fill the bucket with water and stir well
Continuously aerate the mixture with an aquarium air pump
Let the mixture sit out of direct sunlight for up to 3 days. Make sure to stir the mixture every day
Pour the liquid through a strainer to filter out the solids. The resulting liquid can then be used as fertilizer

FAQs
What’s a decent
In the process of making the solution, there are many different methods and processes that can be used to make the solution. The solution can either be made with or without the use of nutrients. If you want to make a nutrient-free solution, it is important to know the amount of water that your plants need to survive.
To make an organic hydroponic solution, you will need some nutrients. You can use a commercial product like Gro-Lite or you can make your own solution. The problem with making the solution is that it requires a lot of time and work. The other problem is that you will end up using a lot of chemicals that will pollute the environment. If you have been growing plants organically for a long time, then you should be familiar with this method. There are many products available on the market that are designed to be used as organic fertilizers. When making the solution, you need to add the fertilizer into the distilled water.
You can use a regular 5 gallon bucket for your hydroponic system. Next, you will need something to use as a nutrient solution. This could be a combination of water, water soluble fertilizer, and some Epsom salt. I usually use 1/4 cup of Epsom salt, 1/2 cup of water soluble fertilizer, and 1 quart of water.
What are the common nutrients for hydroponics?
There are a lot of different types of nutrients available, but I’ve found that the most commonly used ones are:
There are certain nutrients that will work for all plants, such as nitrogen, phosphorous, potassium and magnesium. Others are best suited for specific plant families. For example, copper is known to be good for ferns, while manganese is best for flowering plants. Some of these are also more common than others, so it’s important to know what types of nutrients are most commonly used for each plant family. For instance, in a hydroponic system you wouldn’t use manganese for flowering plants because it can have an effect on the colour of the flowers.
There are certain nutrients that will not work for all plants, and will actually have the opposite effect to what you want. For example, sulphur is known to be harmful to ferns and algae, while some flowering plants need potassium in order to flower. Some other nutrients are very specific and can only be used for a certain type of plant, such as calcium, which is only useful for ferns and cacti. Some of these are also more common than others, so it’s important to know what types of nutrients are most commonly used for each plant family.
What type of fertilizer should you use for a hydroponic solution?
Make sure that the fertilizer you use has all of the elements that you want in your solution. When you add too much nitrogen into the solution, you will have more of a root zone which will slow down the growth of the plant. If you want to make your own hydroponic solution, you should know what nutrients to add. When you start growing plants, you will need to fertilize them once every 2 to 3 weeks.

The red and blue light are a great combination and they are needed as your plant matures. They are especially required for both the vegetative and flowering stages. This red and blue light combination enhances the production of more leaves and crops.
Violet Or Purple Light
Violet light or purple light is an additional light that your plants can benefit from. These colors have the shortest wavelength and high energy which enables the plant to be able to absorb them well. The light energy in the violet color results in a sweet aroma, and great plant color, and is a flavor booster in vegetables and fruits.
Therefore, you can use this light at any stage of a plant to boost its color and improve its taste. Violet light will also enhance the number of antioxidants in a plant.
Greenlight
The effect of green light on plant growth is not so significant. The reason is that most plants are already green in color and thus will reflect green rather than absorb it.
Yellow Light
Yellow light does not have much effect on the growth of a plant. It is just like green lights which are difficult for plants to absorb.
Ultraviolet Light
Ultraviolet light is known to be harmful to humans. So, just as ultraviolet light is harmful to humans, high exposure is also bad for plants. Your plants will develop with little exposure to ultraviolet light.
How Do You Use Grow Lights For Outdoor Plants?
Light is an absolute necessity for any and every plant, and adequate light is a must for the efficient growth and production of any plant.
Sunlight is the natural and most used source of light for plants. However, sometimes plants even when planted outside may not be able to receive the adequate amount of sunlight that they require to grow. This could be for example, when plants are planted or grow under taller trees or a canopy of trees. It may also be if plants are in an area of a garden that receives short hours of sunlight exposure.
The use of grow lights outdoors is not very common but can be a good way to give plants supplemental light to help improve growth and productivity.
There are several considerations to keep in mind if you are going to use grow lights outdoors;
Because these lights will be outside where they will be exposed to environmental conditions such as rain and winds, make sure you get waterproof and secure the lights properly to prevent them from blowing away.
Be careful to position the lights in a place where they won’t get interference from other plants, shade, etc.
Remember that you do not need to have to grow lights on at all times, put them on a timer so that your plants only get the light that they need. This will also help you save money.
What Plants Don’t Like Grow Lights?
Most plants need light (whether natural or artificial) to grow efficiently. This applies to both indoor and outdoor plants. Most plants would die without getting a bit of light exposure.
There are however certain plants that do well without light and are mostly planted as indoor plants, or in areas that do not have a lot of sunlight. These plants would be good for a beginner who is starting out or still learning how to take care of plants.
Here are some of these plants;
Bromeliad (Bromeliaceae)
Chinese Evergreen (Aglaonema)
Cast Iron Plant (Aspidistra elatior)
Dracaena (Dracaena)
Dumb Cane (Dieffenbachia)
English Ivy (Hedera helix)
Peace Lily (Spathiphyllum)
How Do You Put Grow Lights on Indoor Plants?
The best place to position grow lights on indoor plants is directly above the plants. This is so that the plants can grow upright.
If the lights are placed, for example on the side of the plant, it will lean towards it to “follow” the light which is not ideal. Placing the grow light on top of the plants will help ensure an even distribution of light to the plants. This is the best way to put grow lights on indoor plants.
How Long Should I Leave My Plants Under Grow Lights?
Grow lights do not need to be on all the time. The idea with them is that they should replicate the light conditions that would be provided by sunlight. They aim to create a similar day and night cycle as the natural one.
The length of time you should leave your grow lights on depends on how light-hungry your plants are. So do a bit of research to find out how much light your plant needs for optimum growth and health. Generally grow lights are left on for anywhere between 8-10 hours a day
How Far Should LED Grow Light Be From Plants?
The distance between LED grow lights and plants depends on the intensity of the light. For LEDs of 200 watts should be placed between 12-20 inches, and those of high wattage like 1000 watts should be placed 36-46 inches from the top of the plant.
Does a Plant Grow Faster in Sunlight or Artificial Light?
A plant would grow faster under artificial light than in sunlight. This is because artificial light can be adjusted to best suit the needs of the plant at that specific time, and therefore help to improve the growth and production of that plant.
Why Is Green Light Bad For Plant Growth?
Some studies suggest that green light makes plants behave as if they’re growing in poor environments that have a lot of shade. This could be the cause of plants having stunted growth and development if this green light is used on them.
Green light is reflected by plants, which is why they appear green. And because this green light is reflected, plants absorb very little of it. Because of this, it is thought to have minimal to no use for plant growth, particularly in the processes of photomorphogenesis and photosynthesis.
The role of green light for plant growth is yet to be widely explored as there are no definitive studies on its importance.
Full spectrum LED lights include green light, it is however unclear how useful it is for stimulating growth.
– The topic has yet to be widely studied. While full-spectrum LED lights include green light, it’s unclear how useful green light is for stimulating plant growth.
Currently, many growers use green LEDs to check their plants for things such as pest infestations or damage during the dark cycle of plant growth. Greenlight mimics shade or moonlight, so these lights can be used without interfering with the plant’s cycle.
How Does Blue Light Affect Plant Growth?
Blue light is referred to as radiation and has wavelengths between 400 and 500 nm. This wavelength is in the visible spectrum and has high energy which greatly affects photosynthesis, plant growth, and flowering.
Blue light is not as efficient as other lights in the electromagnetic energy wavelength, it is however still necessary for the growth of plants.
Another important function of blue light is regulating the plant stomata. Stomata are the pores in the dermis or skin of the leaves and stems of plants, which are important for gas exchange. These pores open and close, allowing the intake of carbon dioxide and the release of oxygen. As this process is essential for photosynthesis, it makes blue light necessary.
The shorter wavelength of blue light makes it very important in the processes that increase vitamin levels in plants, the quality, as well as overall plant health. Used in conjunction with red light, blue light can serve as a regulator for plant flowering.
How Does Yellow Light Affect Plant Growth?
Yellow light by itself plays a trivial role in photosynthesis and therefore plant growth or flowering, it is, however, useful in combination with other colors.
Much of the yellow light is reflected together with the green light. Because of this, placing a plant under yellow light will stunt its growth and development. If seedlings are given yellow or orange light alone, they will not be able to create carbohydrates, and so will not grow well or thrive.
In one study, however, yellow light has been found to have a positive impact on bioactive flavonoid accumulation in some herbs. This could mean that it just has not been studied enough and its effects are not well understood yet.
What Color Makes Plants Grow Faster?
Having discussed in detail all these different colors and their roles in plant growth, you are now probably wondering what the best color for plants that will affect their growth is. Simply put, the best color is a combination of red and blue light. Red light helps to increase plant biomass. The blue light on the other hand controls the flow of chloroplasts in the cells, which is responsible for oxygen transmission and also regulates the stomata opening
Blue light is ideal for the early plant stage such as seedlings. As your plant matures, the red and blue light colors are combinations excellent for your plants’ growth. That is why red-blue grow light combinations are popular on the market.
Does The Color Of Light Affect Plant Growth? – Final Say
The colors of light contribute a lot during different growth stages in a plant’s life cycle. Knowing what color grow lights to purchase, and which to use for each growth stage, as well as knowing which colors to avoid is absolutely crucial to the success of your plants.
The extensive information provided in this article will set you well on the path to success with this subject. If you go to a store and are still unsure, ask the light expert at the shop so that you can be more confident with your purchase.
The most important point to remember is that a combination of blue and red light is best for plants, colors such as green and yellow however are not ideal. Full spectrum growth lights are sold with the whole light spectrum, as the light suggests, and you will never go wrong with them.
Happy gardening.
FAQ’s
How does the color of light affect plant growth?
The most important factor in determining plant growth is sunlight. Plants need light to grow. However, the quality of light that they receive has a huge impact on their growth. Light is made up of electromagnetic radiation. The wavelength or color of light determines the color of light. For example, red light (in the visible spectrum) is longer than blue light (in the visible spectrum), which is why many plants absorb it in heaps.
The color of light affects all life on Earth. Light is composed of electromagnetic radiation, including visible light, ultraviolet light, and infrared light. These wavelengths of light are absorbed by plant chlorophyll, which helps plants process sunlight and produce energy. When light is in the blue-green range, it is called blue light. When light is in the red-orange range, it is called red light. When light is in the green range, it is called green light.
When light is in the yellow-orange range, it is called yellow light. When light is in the violet range, it is called violet light.
How does color of light affect photosynthesis?
Color of light affects photosynthesis in a plant. Green and red light stimulate the plant to grow more. Blue light stimulates the plant to grow less. If the plant is not exposed to blue light, it will grow more than if it is exposed to blue light.
What color of light is most effective for plant growth?
The answer to this question depends on the type of plant and its position in the light spectrum. Plants use light to manufacture energy from the sun’s rays, and they use light to make the food they need for survival. The light color that a plant needs is determined by its specific needs for growth and development.
Which plant uses blue light to grow more?
The answer is the plant fern. The plant fern is a small green plant that grows in moist soil. It is very similar to a plant called moss.
What color light is best for germination?
You can use any type of high intensity lighting you want, but the light spectrum emitted by your bulbs matters.
High-pressure sodium bulbs emit more blue light than other types of bulbs. This makes them effective at germination but not so good for later development. Halogen bulbs emit a lot of red and yellow light, which is useful for later growth but may not be effective for germination.
The red and blue light are a great combination and they are needed as your plant matures. They are especially required for both the vegetative and flowering stages. This red and blue light combination enhances the production of more leaves and crops.

The answer is the plant fern. The plant fern is a small green plant that grows in moist soil. It is very similar to a plant called moss.
What color light is best for germination?
You can use any type of high intensity lighting you want, but the light spectrum emitted by your bulbs matters.
High-pressure sodium bulbs emit more blue light than other types of bulbs. This makes them effective at germination but not so good for later development. Halogen bulbs emit a lot of red and yellow light, which is useful for later growth but may not be effective for germination.
The red and blue light are a great combination and they are needed as your plant matures. They are especially required for both the vegetative and flowering stages. This red and blue light combination enhances the production of more leaves and crops.
Violet Or Purple Light
Violet light or purple light is an additional light that your plants can benefit from. These colors have the shortest wavelength and high energy which enables the plant to be able to absorb them well. The light energy in the violet color results in a sweet aroma, and great plant color, and is a flavor booster in vegetables and fruits.
Therefore, you can use this light at any stage of a plant to boost its color and improve its taste. Violet light will also enhance the number of antioxidants in a plant.
Greenlight
The effect of green light on plant growth is not so significant. The reason is that most plants are already green in color and thus will reflect green rather than absorb it.
Yellow Light
Yellow light does not have much effect on the growth of a plant. It is just like green lights which are difficult for plants to absorb.
Ultraviolet Light
Ultraviolet light is known to be harmful to humans. So, just as ultraviolet light is harmful to humans, high exposure is also bad for plants. Your plants will develop with little exposure to ultraviolet light.
How Do You Use Grow Lights For Outdoor Plants?
Light is an absolute necessity for any and every plant, and adequate light is a must for the efficient growth and production of any plant.
Sunlight is the natural and most used source of light for plants. However, sometimes plants even when planted outside may not be able to receive the adequate amount of sunlight that they require to grow. This could be for example, when plants are planted or grow under taller trees or a canopy of trees. It may also be if plants are in an area of a garden that receives short hours of sunlight exposure.
The use of grow lights outdoors is not very common but can be a good way to give plants supplemental light to help improve growth and productivity.
There are several considerations to keep in mind if you are going to use grow lights outdoors;
Because these lights will be outside where they will be exposed to environmental conditions such as rain and winds, make sure you get waterproof and secure the lights properly to prevent them from blowing away.
Be careful to position the lights in a place where they won’t get interference from other plants, shade, etc.
Remember that you do not need to have to grow lights on at all times, put them on a timer so that your plants only get the light that they need. This will also help you save money.
What Plants Don’t Like Grow Lights?
Most plants need light (whether natural or artificial) to grow efficiently. This applies to both indoor and outdoor plants. Most plants would die without getting a bit of light exposure.
There are however certain plants that do well without light and are mostly planted as indoor plants, or in areas that do not have a lot of sunlight. These plants would be good for a beginner who is starting out or still learning how to take care of plants.
Here are some of these plants;
Bromeliad (Bromeliaceae)
Chinese Evergreen (Aglaonema)
Cast Iron Plant (Aspidistra elatior)
Dracaena (Dracaena)
Dumb Cane (Dieffenbachia)
English Ivy (Hedera helix)
Peace Lily (Spathiphyllum)
How Do You Put Grow Lights on Indoor Plants?
The best place to position grow lights on indoor plants is directly above the plants. This is so that the plants can grow upright.
If the lights are placed, for example on the side of the plant, it will lean towards it to “follow” the light which is not ideal. Placing the grow light on top of the plants will help ensure an even distribution of light to the plants. This is the best way to put grow lights on indoor plants.
How Long Should I Leave My Plants Under Grow Lights?
Grow lights do not need to be on all the time. The idea with them is that they should replicate the light conditions that would be provided by sunlight. They aim to create a similar day and night cycle as the natural one.
The length of time you should leave your grow lights on depends on how light-hungry your plants are. So do a bit of research to find out how much light your plant needs for optimum growth and health. Generally grow lights are left on for anywhere between 8-10 hours a day
How Far Should LED Grow Light Be From Plants?
The distance between LED grow lights and plants depends on the intensity of the light. For LEDs of 200 watts should be placed between 12-20 inches, and those of high wattage like 1000 watts should be placed 36-46 inches from the top of the plant.
Does a Plant Grow Faster in Sunlight or Artificial Light?
A plant would grow faster under artificial light than in sunlight. This is because artificial light can be adjusted to best suit the needs of the plant at that specific time, and therefore help to improve the growth and production of that plant.
Why Is Green Light Bad For Plant Growth?
Some studies suggest that green light makes plants behave as if they’re growing in poor environments that have a lot of shade. This could be the cause of plants having stunted growth and development if this green light is used on them.
Green light is reflected by plants, which is why they appear green. And because this green light is reflected, plants absorb very little of it. Because of this, it is thought to have minimal to no use for plant growth, particularly in the processes of photomorphogenesis and photosynthesis.
The role of green light for plant growth is yet to be widely explored as there are no definitive studies on its importance.
Full spectrum LED lights include green light, it is however unclear how useful it is for stimulating growth.
– The topic has yet to be widely studied. While full-spectrum LED lights include green light, it’s unclear how useful green light is for stimulating plant growth.
Currently, many growers use green LEDs to check their plants for things such as pest infestations or damage during the dark cycle of plant growth. Greenlight mimics shade or moonlight, so these lights can be used without interfering with the plant’s cycle.
How Does Blue Light Affect Plant Growth?
Blue light is referred to as radiation and has wavelengths between 400 and 500 nm. This wavelength is in the visible spectrum and has high energy which greatly affects photosynthesis, plant growth, and flowering.
Blue light is not as efficient as other lights in the electromagnetic energy wavelength, it is however still necessary for the growth of plants.
Another important function of blue light is regulating the plant stomata. Stomata are the pores in the dermis or skin of the leaves and stems of plants, which are important for gas exchange. These pores open and close, allowing the intake of carbon dioxide and the release of oxygen. As this process is essential for photosynthesis, it makes blue light necessary.
The shorter wavelength of blue light makes it very important in the processes that increase vitamin levels in plants, the quality, as well as overall plant health. Used in conjunction with red light, blue light can serve as a regulator for plant flowering.
How Does Yellow Light Affect Plant Growth?
Yellow light by itself plays a trivial role in photosynthesis and therefore plant growth or flowering, it is, however, useful in combination with other colors.
Much of the yellow light is reflected together with the green light. Because of this, placing a plant under yellow light will stunt its growth and development. If seedlings are given yellow or orange light alone, they will not be able to create carbohydrates, and so will not grow well or thrive.
In one study, however, yellow light has been found to have a positive impact on bioactive flavonoid accumulation in some herbs. This could mean that it just has not been studied enough and its effects are not well understood yet.
What Color Makes Plants Grow Faster?
Having discussed in detail all these different colors and their roles in plant growth, you are now probably wondering what the best color for plants that will affect their growth is. Simply put, the best color is a combination of red and blue light. Red light helps to increase plant biomass. The blue light on the other hand controls the flow of chloroplasts in the cells, which is responsible for oxygen transmission and also regulates the stomata opening
Blue light is ideal for the early plant stage such as seedlings. As your plant matures, the red and blue light colors are combinations excellent for your plants’ growth. That is why red-blue grow light combinations are popular on the market.
Does The Color Of Light Affect Plant Growth? – Final Say
The colors of light contribute a lot during different growth stages in a plant’s life cycle. Knowing what color grow lights to purchase, and which to use for each growth stage, as well as knowing which colors to avoid is absolutely crucial to the success of your plants.
The extensive information provided in this article will set you well on the path to success with this subject. If you go to a store and are still unsure, ask the light expert at the shop so that you can be more confident with your purchase.
The most important point to remember is that a combination of blue and red light is best for plants, colors such as green and yellow however are not ideal. Full spectrum growth lights are sold with the whole light spectrum, as the light suggests, and you will never go wrong with them.
Happy gardening.
FAQ’s
How does the color of light affect plant growth?
The most important factor in determining plant growth is sunlight. Plants need light to grow. However, the quality of light that they receive has a huge impact on their growth. Light is made up of electromagnetic radiation. The wavelength or color of light determines the color of light. For example, red light (in the visible spectrum) is longer than blue light (in the visible spectrum), which is why many plants absorb it in heaps.
The color of light affects all life on Earth. Light is composed of electromagnetic radiation, including visible light, ultraviolet light, and infrared light. These wavelengths of light are absorbed by plant chlorophyll, which helps plants process sunlight and produce energy. When light is in the blue-green range, it is called blue light. When light is in the red-orange range, it is called red light. When light is in the green range, it is called green light.
When light is in the yellow-orange range, it is called yellow light. When light is in the violet range, it is called violet light.
How does color of light affect photosynthesis?
Color of light affects photosynthesis in a plant. Green and red light stimulate the plant to grow more. Blue light stimulates the plant to grow less. If the plant is not exposed to blue light, it will grow more than if it is exposed to blue light.
What color of light is most effective for plant growth?
The answer to this question depends on the type of plant and its position in the light spectrum. Plants use light to manufacture energy from the sun’s rays, and they use light to make the food they need for survival. The light color that a plant needs is determined by its specific needs for growth and development.
Which plant uses blue light to grow more?
The answer is the plant fern. The plant fern is a small green plant that grows in moist soil. It is very similar to a plant called moss.

Different Color Grow Lights And Their Functions
Blue, red, green, yellow, and a couple of other light colors are essential in the plant’s life cycle. Let’s take a look at some of these colors and how they will affect the growth of your plant:
Blue Light
Blue light has a short wavelength and high energy in the color spectrum which makes it easy for plants to absorb it. It is very important for the early plant stage such as seedlings and some seeds may not germinate if this blue light is not present. This is the light to be used when your plants are beginning to sprout.
Blue light is easily assimilated by plants which they convert to energy to attain maturity faster. A blue light will also enhance the quantity of chlorophyll that is produced by your plant.
Red Light
Red light has a long wavelength therefore their energy level is not so great for plants. Now, red light is usually very effective on plants when combined with other light colors such as blue. The combination is ideal for mature plants that may be undergoing phases such as the flowering phase.
The red and blue light are a great combination and they are needed as your plant matures. They are especially required for both the vegetative and flowering stages. This red and blue light combination enhances the production of more leaves and crops.

A commonly asked question among growers is; “does the color of light affect plant growth?” The answer is yes! Light color sure affects plant growth and we will be discussing why this is so.
Light is one crucial factor required for the optimal growth of plants. It is important for the reaction and activities that go on in your plants, which are required for their proper development. The color of light affects the growth and productivity of plants in many ways and we will be discussing this in more detail.
How Does The Color Of Light Affect Plant Growth?
The light that your grow light emits comes in different spectra for use towards your plants’ growth. The color of grow light you supply your plant will not only affect your plants’ growth but will also determine the result of their development.
The process of photosynthesis where plants make their food requires the use of light. Also, chlorophyll is responsible for the green pigmentation of leaves and stems. It requires light to transform carbon dioxide into food and this is done by the energy provided by light.

The color of light affects all life on Earth. Light is composed of electromagnetic radiation, including visible light, ultraviolet light, and infrared light. These wavelengths of light are absorbed by plant chlorophyll, which helps plants process sunlight and produce energy. When light is in the blue-green range, it is called blue light. When light is in the red-orange range, it is called red light. When light is in the green range, it is called green light.
When light is in the yellow-orange range, it is called yellow light. When light is in the violet range, it is called violet light.
How does color of light affect photosynthesis?
Color of light affects photosynthesis in a plant. Green and red light stimulate the plant to grow more. Blue light stimulates the plant to grow less. If the plant is not exposed to blue light, it will grow more than if it is exposed to blue light.
What color of light is most effective for plant growth?
The answer to this question depends on the type of plant and its position in the light spectrum. Plants use light to manufacture energy from the sun’s rays, and they use light to make the food they need for survival. The light color that a plant needs is determined by its specific needs for growth and development.
Which plant uses blue light to grow more?
The answer is the plant fern. The plant fern is a small green plant that grows in moist soil. It is very similar to a plant called moss.
What color light is best for germination?
You can use any type of high intensity lighting you want, but the light spectrum emitted by your bulbs matters.
High-pressure sodium bulbs emit more blue light than other types of bulbs. This makes them effective at germination but not so good for later development. Halogen bulbs emit a lot of red and yellow light, which is useful for later growth but may not be effective for germination.

Imagine an instance where you’ve got everything ready for your indoor hydroponics farm and this question pops into your mind; how many watts per plant for LED grow lights should I provide my plants with? If you do not know how to answer this question, this post will help you determine the wattage to provide your plants so that they grow optimally under your LED grow lights. Let us begin.
Wattage as Plant Indicator for Grow Light
Wattage in the real sense shouldn’t be the actual indicator for your grow lights. It does not determine the amount of energy your plant receives to grow. You should only use watts as a guideline for working out the energy of grow light fixtures that you should use.
One of the keys to successfully growing your plants in a given area using grow light intensity is getting to know and understand the light spectrum.
Watts will however help you calculate or determine the amount of electricity consumed by the grow lights. This will help in terms of knowing your costs, and possibly working out cost-saving methods if you need to. However, if we look at it this way; more energy consumption results in more light for your plants’ growing needs. We can then assume wattage to be an indicator.
How Many Watts Per Plant LED Grow Lights?
Let’s take a look at this using square feet per plant. The first thing you need to do is measure the size of your grow space or tent by square feet. After you have determined the area, use this measurement to purchase the LED grow light of appropriate light intensity. If you are still unsure, you should consult the light specialist at the light store.
Note that other factors may also determine your choice of LED to-grow lights. These factors will help in choosing the appropriate light intensity required for the growth of your plants.
Factors for choosing LED to grow light per plant
How many watts your plants will require will vary depending on these factors:
Type of plant: the type of plants will fall into the category of high light demanding or low light demanding. High-light demanding lights include peppers, tomatoes, etc. While low light-demanding plants include leafy greens and herbs such as lettuce, basil, watercress, kale, etc.
Grow space or tent: the area of your grow space will determine the number of watts needed. A large grow space or tent will demand more power while a small grow space will demand less.
Growth stage: the various stages of a plant’s life cycle will also determine how many watts for LED grow light are required. The various growing stages are seedlings, vegetative, flowering, and fruiting which all require a different amount of light.
Deciding on the appropriate light per square meter of your grow space or tent is crucial. The various sizes of your grow room or tent will require different intensities of light.
Here are the recommended watts per square foot of a plant:
2 by 2 feet (4 sq. ft) will require between 120 to 140 watts.
2 by 4 feet (8 sq. ft) will require between 240 to 280 watts.
3 by 3 feet (9 sq. ft) will require between 280 to 340 watts.
4 by 4 feet (16 sq. ft) will require between 420 to 480 watts.
4 by 5 feet (20 sq. ft) will require between 600 to 650 watts.
5 by 5 feet (25 sq. ft) will require between 780 to 840 watts.
6 by 6 feet (36 sq. ft) will require between 1000 to 1200 watts.
Generally, you should know that the number of watts increases by square feet. This also depends on how many plants will be grown in this area.
Let’s take a look at how many watts per square foot using the number of plants grown in a particular area.
1 plant per square foot will require 30 to 40 watts.
2 plants per square foot will require 60 to 80 watts.
8 plants per square foot will require 240 to 300 watts.
10 plants per square foot will require 300 to 340 watts.
Manufacture’s Watt vs Actual Watt
The LED you find in the market will have their printed manufacturer’s wattage. However, the actual watt to run it is usually different.
For instance, if it goes for 3-watt diode electric power and you run it by that 3 watts; you will be drawing or burning out all the power. The recommended usage should be around 60% power of what is given or listed.
How Many Watts Per Square Foot for LED Grow Lights?
The general rule of thumb with grow light wattage is 32 watts per square foot of LEDs. Thirty-two watts should be enough to cover every inch of that square foot. You can go a bit lower to 30, and higher to 40, but these limits should not be exceeded.
This should be the goal, but to get the best results, it would still depend on a variety of other growing conditions that you have. These include the number, type, and size of plants that you have. What matters the most is that the right amount of usable light reaches each square foot of the growing area.
To calculate the correct amount of wattage that will reach your grow room space, you must first accurately identify the size of your grow room. Wattage, however, should not be the determinant of your coverage area, and it should not dictate the effectiveness of the grow light that you get. It should only be used as an approximation to get the correct fixture for your growing space. This means that you must use wattage to guide you on how much power your grow light can give per square foot of the grow room.
Photosynthetic Photon Flux Density or PPFD, measured in μmol/j/m2, and DLI (Daily Light Integral) are the appropriate metrics for measuring light intensity over a specific growing area.
The PPFD measures the total amount of light that is emitted by a light source per second. It also indicates how much light intensity (PAR) you need to grow your plants is created.
How Many Watts of Light for Seedlings?
Seedlings generally require about 32 watts per square foot of seedlings for LED grow lights and 100 watts per plant for CFLs. On top of this, they also require the right color temperature to grow and thrive. The ideal temperature you should choose is in the range of 3500 to 6500 kelvins.
It is important to keep in mind that “watt” measure the amount of energy that light uses, not how much light is emitted. Yes, the wattage will give you an indication of how much light will be emitted. It is important to understand this while choosing lights for seedlings.
Another important factor to consider is the distance at which you should place your grow lights, from the seedlings. Ideally, the space should be 6 inches to get the best results. For easy movement of the lights, you can create or build some system using chains that will allow you to suspend the light fixtures. You can also mount your lights somewhere and elevate the plants on a table or something similar to this seed starting station.
To keep your grow lights working efficiently over a long period, you must consistently wipe down the light tubes to remove dust, grease, and grime before using them each year.
Regardless of the type of light bulb you use for your grow lights, using lumen output to determine the right grow light use for seedlings might be better than using watts. The general rule with lumens; the higher the number of lumens, the brighter the light will be.
Conclusion – How Many Watts Per Plant for LED Grow Lights?
This article has provided you with all the information you need to understand the concept of growing light wattage used for growing plants. The rule of thumb is 32 watts per square foot of growing area. But remember to take into account the other factors that come into play when choosing a grow light. Familiarize yourself with the information provided here and you are well on your way to mastering grow lights.
With that said, we hope you can figure out how many watts for each plant LED grow light are required to get optimum growth.

Wondering if black light for plants works? Plants require light to grow, be it artificial light or natural sunlight. Now, this light comes in various colors of the spectrum. Different light colors are required by your plants at their various stages of growth.
Ultraviolet (UV) light is also emitted in the light spectrum and some forms of it are absorbed by ozone, water vapor, oxygen, and carbon dioxide in the atmosphere. It is the black light that emits UV radiation and we will be talking about its effect on plants’ growth.
Ultraviolet Black Light for Plants Growth
As we said, a black light emits UV light. The types of UV light produced by black lights are UVA and UVB. Various light wavelengths are absorbed by chlorophyll and phytopigments known as photosynthetic pigments. The lights are assimilated and help to carry out the process of photosynthesis.
Among all the colors of light, chlorophyll vigorously assimilates the blue region more. However, chlorophyll also has strong assimilation for some ultraviolet spectrum portions. The longest wavelength which is found in UVA is firmly assimilated by plants.
Effect of Black Light (UV Light) on Plant Growth
The effect of UV light varies with different plants. You need to be cautious if you wish to use black lights to help support your plants’ growth. This is because too much UV radiation can cause great harm to phytopigments.
Growing plants under black lights alone in the absence of white light may be damaging. You will be depriving them of benefiting from other colors of light. Your plants may grow with a blacklight but they will start to grow leggy because they are missing other colors.
Also, your plants’ chances of blooming with black lights are very slim. However, in a safe dose, your plants may benefit from ultraviolet black light.
Effect of UV light on microorganisms
Microorganisms in plants offer both good and bad effects. There are some microorganisms such as bacteria that affect plants negatively by causing rust and wilting, which give rise to diseases. Ultraviolet light can help kill these harmful bacteria, as well as other pathogens.
However, we also have some beneficial bacteria such as the nitrogen-fixing bacteria present in plants. They help fix the nitrogen used by plants. Ultraviolet light always ends up destroying beneficial microbes which play a vital part in the development of your plants. Thus UV is not ideal for the use of killing microbes.
Effect of UV light on plant DNA
Generally, it is well known that UV rays are pretty damaging to any life form. Now, UV rays are damaging to proteins, DNA, and lipids. So, if the DNA of a cell gets impaired, the genetic substance depreciates and this may bring about mutations or programmed cell death.
Although the damage done to the DNA may usually not be adverse, it may end up causing mutation in plants. Now, a mutation in plants may give rise to significant diversity which can result in better adaptable plants or even organisms.
But generally, plants don’t really need UV light because it actually brings more harm than good. But in a situation where plants end up getting UV light, it forces a reaction that protects plants and ends up boosting certain properties in them.
UV resistant crops
The earth continues to experience some climatic crises. This has been causing the ozone layer that protects the earth from the sun’s UV rays to deplete. Our worry is how damaging can this be to both humans and plants.
The good news is that researchers have been working on the effect of UV on crops and how they can be protected. Researchers have conducted laboratory experiments showing that plants are adapting. It shows that outdoor plants exposed to more UV rays have begun generating molecules to obstruct UV lights.
Therefore, plants can now thrive in severe climatic conditions. At the same time, plants can use UV light to their advantage to fight diseases bothering the plant.
However, UV light is generally detrimental to plants and the negative effect of UV black lights outweighs their advantages.
Are Black Lights and Grow Lights The Same?
Grow lights typically contain a good mix of light in different wavelengths that plants need for growth. This is including the black light that emits UV. Some grow lights naturally emit UV through chemical exchange. Grow lights such as HIDs and T5 grow lights. LED grow lights,s on the other hand can be built with specialized UV-B bulbs or diodes to give them the UV (to give off UV-B) they do not naturally come with.
Ultraviolet light is inane wavelengths of between 320 and 400 nanometers. Unlike lights in other wavelengths that are visible to the human eye, many birds and a small number of humans can perceive light in this wavelength.
Do Plants Need UV Light?
There are different perceptions and opinions about the usefulness of UV light for plants.
Plants that are grown with the use of black lights alone usually will suffer from numerous consequences because of being deprived of natural light.
Excessive UV radiation can have negative effects on plant phytopigments. Some studies have found that removing UV light from white light sources would improve plant growth.
Blacklightt emits UV radiation in the UVA and UVB regions. Chlorophyll from plants strongly absorbs long wavelengths in the UVA region. From this perspective, it is safe to assume that black light would not be ideal for any plant. Plants grown under black light tend to grow poorly or fail to grow at all.
There are however certain benefits that have been observed with the use of UV light for plants. Moderate UVC can kill certain plant pathogens. An excess,s however, can kill beneficial microbes that play a positive role in the growth of plants and other important organisms. Some plants have been specifically found to benefit from the use of UV light. One of these plants is Marijuana. In marijuana, UV light increases the production of CBD and THC, as a coping mechanism to protect the plant from harmful UV radiation. CBD and THC are the active ingredients of the plant. Because of this, LED grow lights used by marijuana growers have UV added to them.
Are Black Lights Bad for You?
As we have discusses, there are different types of black lights or UV lights. There is UVA, UV, B, and UVC. Of these three types, the short wavelength UVC is the most damaging to humans. Fortunately, it is filtered by the atmosphere before it reaches the earth’s surface. Medium wavelength UVB is biologically active, but cannot penetrate past the top layers of the skin.
Prolonged exposure to UV light emitted by black light can be harmful. It can potentially be damaging to your eyes and can affect your vision over time, as well as your skin.
For example, long periods spent in direct exposure to UVA light, such as in tanning beds have been found to cause skin damage.
If you have to work with UV lights in enclosed growing spaces, be sure to wear protective clothing or materials to reduce the risk of damage to your skin and eyes.
How Long to Leave UV Light on Plants
All plants differ in the amount of UV that they require, and can cope with. These differences are present even in plants of the same strain.
Because of these differences, the best way to start is to expose your plants to just 2 hours per day of UV light. It might be best to even split these into 2,1-hour stints. You can increase this time by 15 minutes every two days. If you notice that the top smaller leaves are burning a little, reduce the exposure time by about 30 minutes per stint.
Diligently following this procedure will allow you to get the best out of giving your plants UV light, without causing any damage to them.
The Best UV Light for Indoor Plants
If you grow plants indoors, you should be supplementing your plants with some UV light. UV light can help with plant growth in several ways. It can also help with the potency and overall quality of plant flowers.
However, there are only certain types of UV light that are beneficial to plants. Remember, UV is broken down into 3 categories, i.e. UVA, UVB, and UVC. Only UVA and UVB are essential for certain parts of life on earth, but UVC is not.
A bit more about UVA and UVB;
Ultraviolet A (UVA)
UVA light is in wavelengths between 320 nm and 400 nm. It contains approximately 3% of the photons that are present in natural sunlight that comes through the earth’s atmosphere. This type of UV has no harmful effects on DNA.
Ultraviolet B (UVB)
This type of UV is in wavelengths between 29 nm and 320 nm. It contains about 1/5 of 1% of natural sunlight. Unlike UVA, UVB can cause damage and can cause cancer in humans and animals.
When it comes to providing your plants with UV light, the best way to do it is to get a high-quality UV-to-grow light. Many full-spectrum LED lights emit just the right amount of UV. They also mimic natural sunlight, so they will be great and make your plants feel as if they are growing outside.
There are other lights that such as ceramic CMH grow lights which emit UV light, this is along with some double-ended bulbs.
With all these options, it can be confusing to know which light to choose. Here are four lights that we recommend for you;
Another factor to consider when using a UV light for your plants is to use it in small doses over the entire life of the plant, instead of using it in high doses. This way, it will be safer and more effective.
Final Note – Black Light For Plants
As you have read from this article, there are specific uses, and ways to use UV light for plants so that it does not lead to damage. It can be beneficial in some cases and detrimental in others. Therefore, before you use any black light on your plants, determine whether or not your plants need it, and how best to expose your plants. If you use black light appropriately, such as in conjunction with other light colors, it has the potential to greatly benefit your plants.
FAQs
Does ultraviolet light help with Plant Growth?
The answer depends on what you are growing. The most common UV wavelengths used for indoor horticulture are 365nm, 390nm and 385nm. If you are growing plants that require a lot of light, such as tomatoes, peppers or cucumbers, then the plant will be able to grow normally with a certain amount of UV light.
However, if you are growing plants like broccoli, kale, Brussels sprouts, spinach, cabbage, carrots, parsley, basil, lettuce and other leafy greens, then you will need more than the standard UV dose that comes from the sun. If you are growing these plants, you can use an UV lamp, which is available at nurseries and hardware stores. The UV light for horticulture comes in three different wavelengths: 365nm, 390nm and 385nm. These three wavelengths are used for different types of plants. Some plants require UV light at all times while others require it only in the daytime. The most common wavelength used for indoor horticulture is 365nm. This is because the 365nm wavelength has been proven to be the most effective in providing the optimal amount of light for plants.
What’s the relation between UV and plant growth?
Ultraviolet (UV) radiation is part of the electromagnetic spectrum, which includes visible light, radio waves and X-rays. It consists of wavelengths shorter than that of visible light, but longer than those of X-rays. Ultraviolet radiation comes from the Sun, and it can also be generated artificially by high-intensity light bulbs. Ultraviolet radiation is important for plant growth and development because it helps in regulating the balance between the processes of photosynthesis and photorespiration.
How sensitive are plants to black lights?
Ultraviolet (UV) radiation is a form of solar radiation that can cause sunburn, skin cancer and other serious health problems. UV-B radiation causes skin cancer and cataracts; UV-A radiation is responsible for tanning of the skin. Although most plants are sensitive to UV-B radiation, some species have evolved ways to protect themselves against it. The same protective mechanisms apply to UV-A radiation, but they are not as widespread in nature.
Sunlight is composed of visible light, ultraviolet (UV) light and infrared light. The spectrum of UV light is divided into three bands: UVA, UVB and UVC. The UVA band, with wavelengths between 320 and 400 nm, penetrates the atmosphere and reaches the earth’s surface.
Does it affect the DNA od plants?
Not always, but it can cause mutations and damages. You should research which plants are resistant to UV rays and which ones are not.
