Do you know how to make a recirculating DWC system? Well, we’ve got you covered here. Recirculating deep water culture also known as RDWC imitates the traditional deep water culture (DWC) by just adding a few modifications.
Deepwater culture is a type of hydroponic system that ensures your plants have constant access to water, nutrient solution, and oxygen all at once. There are also measures put in place for adequate aeration for optimal plant growth.
Setting up your recirculating deep water culture system is pretty easy when you have the right knowledge. This article will go over what you need to know about how to make a recirculating DWC system and many more. So, read on to learn about this.
Recirculating Deep Water Culture
Recirculating the DWC system works just like deep water culture, however, there are a couple of things that will be redesigned. Both RDWC and DWC have their plant roots immersed in nutrient solution and oxygen-filled solution.
The main advantage and difference to recirculating the DWC system are that it’s ideal for large-scaling hydroponic farming. Therefore, several plants can be grown together with the recirculating deep water culture system.
Recirculating deep water culture system works by tubing several buckets or containers. All these containers are connected to a central reservoir.
The major difference between RDWC and DWC is that nutrient solution gets recirculated in recirculating deep water culture. The nutrient solution moves or circulates from one container to the other and finally the reservoir. But in the traditional DWC, the water does not move and it stays in the container.
DIY Recirculating DWC System
Here, we have outlined the process you can follow when it comes to how to make a recirculating DWC system. So let’s begin:
Materials required
Let’s first take a look at the materials required to build your recirculating DWC system:
5-gallon dark-colored buckets with lids (with a drilled hole of about 3 inches)
Net cups of size 3 inches as the drilled hole
Grow medium (e.g. perlite, Hydroton pebbles, coco coir, and so on)
Follow this procedure to learn how to make a recirculating DWC system:
1. Reservoir
Choose the reservoir where you will be storing your hydroponics nutrient. The inline pump should be set inside your reservoir. Also, an air pump and air stone should be in your reservoir.
2. Set up your buckets or containers
Determine the number of buckets or containers you will be using for your recirculating DWC system. The buckets should have lids where you will make a cutting for your net pot to fit in. Inside your net pots, fill them with your preferred growing medium and this is where your plant will be.
Also, holes should be cut on each side of your bucket and connected to your pipe. This pipe will connect to other buckets and back or down to your reservoir. Each bucket or container must have its air stones.
3. Position your plant
You can grow your seeds indoors with net pots that contain a growing medium and transplant them into your RDWC system. You can grow about 2 or 3 plants in each container. Note that your net pot should have a wide mesh at the base so that the plant root can touch the nutrient water container.
4. PH balancing
The next thing is to balance the pH. Different plants require different pH ranges to grow adequately. However, the general pH range for plants is around 5.5 to 6.5.
So, your recirculating deep water culture system is ready to run. If later on, you decide to add extra containers or buckets, you must also add more nutrient solutions to the reservoir. This is to ensure each plant gets the appropriate amount of nutrients to grow optimally.
We also recommend you have 3 plants maximum for each container so your plants can get a sufficient amount of nutrients and oxygen. Having more than 3 plants may increase the risk of nutrient and oxygen competition which can diminish each plant’s survival rate.
How Does RDWC Works?
Recirculating DWC systems always have their plant root submerged in water. But usually, plant roots don’t always like their roots immersed in water; especially all day as they can suffocate. But why is it different in the deep water culture system? Well, let’s find out.
We have 3 major components and keys to the RDWC system and they are:
Oxygen: The most essential part of both deep water and recirculating deep water culture systems is oxygenation. This is because we have plant roots always immersed in water. Therefore, you need to provide all means of oxygenation so your plant does not choke. So, the use of air pumps and air stones solves this air circulation problem.
Water: We can see that water is a great factor in the structure of the RDWC system. Plants are always being fed oxygen-rich water thereby taking away the need of watering your plants constantly as you would have in traditional soil.
Nutrients: Another great component that makes your RDWC system work perfectly is the hydroponics nutrient supplied to your plants. The nutrient originates or comes from the major reservoir and passes along the pipes to reach each connected container.
RDWC and DWC System: Major Difference
So, in the recirculating deep water culture system, the nutrient-filled water is reused and is not drained. However, the traditional deep water culture nutrient solution always remains in the container. Recirculating DWC also allows for large scaling, unlike the traditional deep water culture system.
Bucket Hydroponic System: How to Make Your Own
You may be wondering how to make your own 5-gallon hydroponic bucket system. If this is the case, then look no further! For this guide, you’ll need the following equipment:
5-gallon bucket
net bucket lid
water pump (ideally, aquarium)
air hose
check valve
clay pebbles
air stones (at least 6 inches in size)
Now all you need to do is:
The first thing you need to do is cut a small amount of your air hose (around a few inches or so). To one end, attach to your pump. Now you’re going to attach your air hose to the check valve. Ensure that air can run freely through your valve before moving on to the next step.
With the rest of your hose, cut a piece that is long enough to reach both the check valve and the bottom of your bucket. Try not to make the space between the two more than around 5ft. If the space between the two is too long, it won’t work as efficiently as it should.
Grab your net bucket lid and drill a hole. The hole should be big enough for your hose to go through. Then add your air stone, as well as the lid, and then connect to your air hose.
Now you’ll need to add your clay pebbles to the net pot, as well as whatever it is you’re planting. Then water and add nutrients. It is that simple!
Best 2 Bucket DWC System
When it comes to a 2 bucket DWC system, there are many options you can choose from. But the one from PA Hydroponics is my personal favorite. It comes already drilled and ready to assemble, with all the components you need. It costs around $80 and includes two buckets, 2 bucket lids, 1 bag of clay rocks, an air pump, 2 air stones, 10ft of the airline, 2 water indicator kits, and 4 starter plugs. You can also choose to drill it yourself, which will save you around $15.
Best Water Pump For Hydroponic Systems
The water pump is very important to your hydroponic system, so you’ll need to invest in a good one. If you’re looking for a good one on a budget, I would choose the VicTsing 80 GPH Submersible Water Pump.
It holds less than 20 gallons and weighs just under 6oz. It has an adjustable flow and a cord length of just under 6 feet. It also comes with two adapters: 1/2″ and 3/8″. It’s popular among growers because of its unbeatable price. It may be small but it definitely does the job.
Another amazing pump is the Hydrofarm Active Aqua 400 GPH Submersible Water Pump. It can hold up to 40 gallons and weighs just under 3lb. It has an adjustable flow and comes with two tubing fittings: 1/2″ and 3/4″. This is much bigger than the first option, and also much pricier; so it may not be best if you’re a beginner to hydroponic growing.

FAQs
How do you build a recirculating hydroponic system?
There are two main options when it comes to building a recirculating hydroponic system. You can either build a completely self-contained system or you can have a water system that is connected to your home’s existing plumbing. When it comes to a completely self-contained system, there are many different options when it comes to building your own hydroponic system. If you want to save some money, you can buy a pre-made hydroponic unit from a local garden supply store.
You can use a pump to recirculate the water through the system. The water should be filtered before entering the pump, and also after leaving it (if using an air-lift pump). If the pump is attached to a drain, you’ll need to make sure the drain is not clogged with debris or any other material that would cause blockage. You could also use a sump pump with a hose to pump the water back into the tank.
Hydroponics is a term used to describe the growing of plants in water using a nutrient rich solution. It is a form of cultivation that can be used to grow vegetables and herbs indoors in controlled environments.
The advantages of this method are the ability to produce large quantities of high quality vegetables and herbs in an indoor environment. The major disadvantage is that it is more labour intensive than traditional methods. I’m not talking about the time it takes to clean up after harvesting, but the initial setup and maintenance of the system.
How does a recirculating hydroponic system work?
A recirculating hydroponic system is a method of growing plants that involves using water and nutrients to nourish plants in a closed system. It is a very efficient way of growing plants, and can be used to grow a wide variety of plants.
The water is pumped into the grow room, and then circulated through a nutrient solution by means of a pump. The pump draws the solution from the reservoir, and pushes it through a series of filters and pumps that carry the solution to where it can be distributed evenly to the plants.
A recirculating hydroponic system is one of the most effective methods for growing healthy plants indoors. It requires no soil, making it perfect for people who have allergies or other concerns about soil-based plants. The nutrient solution is constantly recirculated, providing a constant supply of fresh nutrients and oxygen to the roots. The only thing that goes out of the system is water. The process The key to a successful recirculating hydroponic system is the design of the system. A simple setup will not work, and will need to be modified or replaced over time. This is because the roots of the plant grow and develop differently as they grow. A large number of plants will also require a different system. As a general rule, the size of the system should be proportional to the space you have available.

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.

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.
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.
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.

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.

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.

Tilapia water temperature requirements in aquaponics are an essential aspect of rearing healthy and vibrant fish. Tilapia is one of the most famous and much-loved fish among aquaponics farmers. They are pretty forgiving when it comes to adaptation generally. However, the temperature requirements of the fish are pretty demanding because they are temperature sensitive.
Tilapia is a warm water fish. When it comes to using tilapia for your aquaponics setup, you need to be aware of tilapia temperature requirements in your aquaponics system. This way, you will enjoy a fantastic growth of tilapia, a reasonable production rate, and a smooth maintenance aquaponics system.
In this post, we will explore tilapia water temperature requirements so read on to learn.
What Are Tilapia Temperature Requirements?
Firstly, you should know tilapia fish is very tolerant of environmental conditions. They can adapt to a poor or substandard water quality environment. They are not food selective and they can feed on nearly anything edible. But they are very sensitive when it comes to temperature.
The ideal temperature for tilapia is in the range of 75 degrees Fahrenheit to 86 degrees Fahrenheit.
Most tilapia fish are temperature sensitive and if the water temperature in your aquaponics drops to 68 degrees Fahrenheit, they will be stressed and the growth of your tilapia fish will depreciate. Now, if the temperature drops below 50 degrees Fahrenheit, your tilapia fish metabolism will be super slow and the survival rate may be pretty low if the issue is not fixed quickly.
If the temperature then falls below 40 or even 30 degrees Fahrenheit that will be a terrible time for your tilapia fish and they will most likely die.
The stress caused by temperatures below 50 degrees Fahrenheit leads to a loss of disease resistance thus exposing or leading to tilapia infection caused by fungi, bacteria, and other pathogens that may be present in the water.
Therefore, ensure you always keep the temperature of the water in your aquaponics system in the right range for your tilapia fish.
Tilapia fish originated from Africa or tropical regions, and as such have warm temperature requirements. Therefore, in other cooler regions, especially in the winter months, you must adjust the tilapia fish’ environment temperature to suit their requirements.
Dealing With Tilapia in Colder Regions
For all-year-round tilapia fish aquaponics systems, recirculating indoor systems are ideal. This is because, in recirculating aquaculture systems, the water or environmental temperatures can be manipulated to suit the needs of the fish that is being grown. It is unlike in natural systems where the fish has to adapt to the environment.
The advantage of adjusting water temperature in recirculating aquaculture systems had additional benefits that may not be immediately apparent. The ideal water temperature in the system will help promote fish growth and feed utilization. In this way, you will get well-growing fish and not waste money on fish feed that is not being well utilized.

You can also introduce an emergency heating just in case the climate snaps and gets you by surprise and you are unavailable or not close by. I’m sure you wouldn’t want to let the amazing aquaculture setup that you have nurtured for a good period go down the lane by just a snap of climatic change, would you?
However, if you do not wish to spend too much money on heat, you can simply opt for the breed of tilapia fish that can tolerate cold or simply go for trout fish, although trout is a bit more sensitive to poor water quality.
Tilapia Water Temperature Adaptation With Cold Water
It is not uncommon to see tilapia fish adapt to their environment being that they are quite forgiving. There are various species of tilapia fish. From generation to generation, they might adapt and withstand temperature changes over time.
Some tilapia breeds have shown good tolerance to temperature changes. An example of cold-hardy tilapia species is the blue tilapia (Oreochromis aureus). The blue tilapia can do well from 45 degrees Fahrenheit. Therefore, we recommend you opt for this type of species if you wish to raise tilapia in a cooler region.
Nonetheless, when kicking off with raising your tilapia fish, especially the ones that were mailed or given to you by anyone – ensure you maintain a warm temperature of at least 60 degrees Fahrenheit.
Blue tilapia is a benthopelagic and potamodromous fish. It ideally prefers tropical climates but it is a fairly cold-tolerant fish. This fish has a wide temperature tolerance range of 46-86 degrees F. It is also tolerant to both freshwater and brackish waters.
How Cold Can Tilapia Survive?
Most tilapia species will survive temperatures below 68 degrees F. You can grow tilapia in these temperatures if you do not mind the reduced growth rates and poor feed utilization. You should however never keep tilapia in temperatures below 55 degrees F.
At much colder temperatures, tilapia as with other fish will become more susceptible to diseases and infections from opportunistic pathogens that may be present in the water. If the temperatures drop even lower, the fish will die.
Here are some of the low-temperature tolerance ranges of tilapia species:
Tilapia Sparrminii (banded tilapia) – 42-44 degrees F
Oreochromis Mozambique (Mozambique tilapia) – 45 degrees F
Tilapia rendalli (Redbreast tilapia) – 53-55 degrees F
Oreochromis niloticus (Nile tilapia) – 53-55 degrees F
The most cold-tolerant tilapia that is known is the vlei kurper, Tilapia sparrmanii, a dwarf tilapia that naturally occurs in the Orange River north and eastward of the Kwazulu Natal Province of South Africa. This tilapia can tolerate temperatures as low as 42 degrees F.
The resilience of tilapia allows them to be cultivated in a wide variety of climates, including those with cooler temperatures. Fish farmers and breeders need to consider the cold temperature tolerance of the tilapia species that they are growing. It is also best to keep all other environmental conditions to minimize the stress that fish are exposed to. Although growing tilapia in colder climates is challenging, it is possible.
How Hot is Too Hot For Tilapia?
Tilapia are warm water fish, but just like all other fish, have an upper tolerance limit or a maximum temperature that they cannot withstand. If they are exposed to these temperatures, especially for long periods the fish will be negatively affected and may eventually even die.
To get good production from tilapia, you must keep your temperatures between 70 and 85 degrees F. These temperatures will give you the best production.
Temperatures higher than these will lead to slow growth, reduced feeding efficiency, and increased mortalities.
Conclusion – Tilapia Water Temperature Requirements In Aquaponics
Tilapia water temperature suitability has a wide range, making these fish easy to cultivate in a variety of climates. As we have pointed out, tilapia species are warm fish. The conclusion is that the ideal temperature requirements of tilapia range from 75 degrees Fahrenheit to 86 degrees Fahrenheit. Temperatures below 50 degrees are fatal for your tilapia fish. Temperatures matter a lot when it comes to raising tilapia fish. So if you wish to enjoy optimal growth and a smooth aquaponics system, get the temperature right.
So, we can see that raising tilapia fish in a colder region is not impossible, although tricky. You just have to go for the appropriate tolerant species like the blue tilapia. This is because they can withstand temperatures around 40 degrees Fahrenheit. Also, you can simply create a comfortable environment for your warm loving tilapia by making use of the indoor recirculating aquaponics system. This can save heat for your tilapia fish during the cold season.
We also recommend you have a backup or emergency heater so climatic change doesn’t meet you or your tilapia by surprise.
FAQ’s
What temperature does tilapia need to grow?
Depends on how old they are. If they’re a year old or more, you should be fine with a slightly warmer tank. However, if they’re only a few months old, you’ll want to be careful and keep the water at around 80-85F (27-29C).
An adult tilapia will eat food every 2-3 hours. Tilapia are a long-living fish, but not as long-lived as other species. Their lifespan is estimated at up to 15 years in captivity. ATilapia are very easy to breed. They are extremely fertile and can easily produce hundreds of offspring.
Are tilapia good in aquaponics?
Yes, they are fine. They have a lot of benefits when compared to other fish. One benefit is that they don’t require much space. You can buy them from any pet store or online. They are also relatively cheap.
Tilapia doesn’t require any special care and it’s not too picky about its water. It will survive in almost any condition. Tilapia is an ideal fish for an aquaponics system as it will grow well on a plant-based diet.
What temperature kills tilapia?
It is safe for tilapia to be raised at temperatures up to 55°F above the water temperature.
Tilapia is an excellent fish for an aquaponic system. In a proper system, it will do very well. I would suggest that you have the tank filled with water and then add your fish.Tilapia are excellent for aquaculture because they’re hardy, fast growing and easy to raise. They’re also cheap to buy. Tilapia can be farmed by anyone and are popular in many different cultures. Tilapia farming can be carried out indoors or outdoors. You can also rear tilapia in tanks or ponds.
Can tilapia fish survive in cold water?
Tilapia can tolerate cold water and even live in water temperatures down to 0 degrees Celsius (32 degrees Fahrenheit).
They are also very resilient, with the ability to withstand a wide range of salinity levels.
What is the desirable water quality for tilapia?
The ideal water quality for tilapia is free of bacteria and nitrate. Bacteria are naturally present in water. They are normally harmless to fish, but if the water contains high levels of bacteria (such as when a reservoir or pond is over-fertilized), they can cause disease in fish.
Nitrate is a naturally occurring compound found in water that causes blue-green algae to grow in water containing too much nitrate. Blue-green algae are very toxic to fish and may even kill them. Nitrates can also be an issue in lakes, ponds and streams. Most water testing services will do this for you. If you don’t want to go through the hassle of sending your water to a lab, there are kits available that you can use at home. You can also get kits at your local sporting goods store or bait shop.

A U siphon for aquaponics can be an excellent mechanism for efficiently draining your grow beds and ensuring that your system remains healthy. The bell siphon has traditionally been used in aquaponics, so you are probably wondering whether the U siphon could be better than the bell siphon. You will find out the answer to that question in this article, keep reading.
What is The Purpose Of a Siphon?
The basic use of a siphon is to drain water from a grow bed conveniently without having to disconnect the pump. The added advantage of this is that during the siphoning process, nutrients remain available to the plants and the rapid movement of the water ensures that there is a high supply of oxygen in the water and the roots can uptake it.
The process of siphoning may look mystical, but it actually uses the natural law of gravity to suck up the water and expel air from the pipe until all of it is out, and then the water flows out.
Different types of siphons can be used. Because of the choices that are available and the different opinions around them, it can be pretty confusing. Two common types of siphons are used in aquaponics, the U siphon and the bell siphon. Let us get a good understanding of both mechanisms and make a decision.
U Siphon vs. Bell Siphon
The U siphon is convenient, very easy to install, flexible, and can be adjusted as needed. You can install a U siphon internally or externally, making it versatile. The one problem with a U siphon is that it can be quite difficult to fix. So you need to understand the mechanisms of how it works if you are going to do so.
The bell siphon is commonly used by many growers. It however requires some effort. The bell siphon functions as a single unit, limiting the number of moving parts required. The mechanism of this siphon uses gravity and pressure to drain water and will maintain a minimum volume of water in the tank it drains.
The main difference between the two siphons is the installation. The U siphon is quite easy to install and flexible. The bell siphon can be faster and has great draining abilities but it can be difficult to install and prime. It may cause trouble even for experienced users.
A better understanding of these two siphon methods will allow us to decide which to go for. Therefore, let’s dive into the mechanism of the U siphon and the bell siphon.
Mechanism of Bell Siphon for Aquaponics
The bell siphon lets water fill up inside a grow bed. After the water has filled up, the bell siphon drains out water from the grow bed. Bell siphon always sustains a moderate water range and drains excess water back into the reservoir.
The bell siphon operates automatically. It saves you the hassle of manually turning on and off the pump of the flood and drain process. Here is how it works:
Stage 1 (Filling): through the water inlet, water floods continuously into the grow bed filling it up from the water pump.
Stage 1 (Water lock): when the water fills up the stand siphon pipe to the point of overflow, water begins flowing down through the drain tube and forms a water lock. By this time, the air left in the cup has been sucked out.
Stage 3 (Drain): water now drains or flows out of the grow beds. Water from the cup is now sucked out after draining water to a particular level.
Stage 4 (Breaking siphon): now as the water drains out and drops down to the level of the bottom siphon pipe, air enters inside. This relieves or breaks up the siphon pipe pressure and stops the drain of water.
This process keeps on going by filling water into your grow bed and siphoning it out. The flood and drain process continues for an unlimited time except when the pump is stopped.
Mechanism of the U Siphon for Aquaponics
As we mentioned earlier, the U siphon is very easy to install unlike the bell siphon making it a great option for beginners.
The main component of the U siphon is the PVC pipe that drains your growing bed. U siphon pipe has an angle of 45, 90, 90, and 45 degrees elbow and a straight pipe. The adjustable U siphon PVC pipe brings in water and the water level does not exceed the loop height.
The U siphon supplies water in and out of your grow bed. When the water level in your grow bed rises, the water level in your U siphon also rises. The curvature end of the pipe contains air. With the motion of water, this air is drawn out and it activates a suction effect.
Once the level of water gets to the loop or curvature of the U-shaped pipe, water flows out and siphons out by the suction effect. Now your entire grow bed drains out rapidly from the elbow through the siphoning process.
The primary material you need is PVC piping. To install the piping, you will need to:
Drill a hole right at the bottom of the grow bed. You will then need to use either a threaded PVC or hose adapter to make sure that this hoke is tightly sealed. The pointed end of this implement needs to stick outside the grow bed.
After this is done, you will use the PVC pipe to create a loop. The height of this loop will determine the maximum height of the water level, so remember to consider this when making it. make sure that the loop leaves some space between the loop and the top of the grow bed. For a more detailed step-by-step process on how to make a U siphon, you can watch this video.
The use of a U siphon in aquaponics is also referred to as loop siphon aquaponics. This is because of the shape of the siphon. The loop works in a simplistic and automatic, and is used for drain ebb and flow hydroponic systems. As the water rises in the grow bed, the water in the loop also rises.
The aquaponics siphon drain is brought up to where you want the water level in the grow bed to be and then brought back down to the water reservoir. The shape resembles an inverted U shape, hence the name “U siphon”. The U can be squared or rounded at the top, it is up to you to decide on the shape you want.
Conclusion – U Siphon For Aquaponics
There you have it, the comparison between the U siphon and the bell siphon for use in aquaponics systems. The bell siphon is commonly used and easy to understand how it works, however, it can present challenges with installation and priming which can cause significant problems such as flooding if you need to drain your grow beds.
The U siphon on the other hand is quite simple to install and use, once it is installed properly it will automatically prime itself and will drain your grow tanks to where you want the water level to be.
When it comes to aquaponics, for your fish and plants to receive sufficient nutrient quantity, it is important to achieve and sustain the right continuous flow of water. A siphon (be it U or bell siphon) is responsible for this. It is used to drain grow beds and it controls and balances the flow of water throughout the system.
The draining process of siphoning allows the availability of nutrients for your plants. It as well facilitates root absorption of oxygen which will help your plants grow excellently well. A U siphon may b the better option of the two.
FAQ’s
How do you make a bell siphon for aquaponics?
The bell siphon is the device that takes water from the bottom of the fish tank and transfers it into the grow bed.
The first thing that comes to mind is a simple water trap (e.g. see this). You can use a similar design, but with a bigger hole and a larger diameter pipe to get the water out of the tank. Then, you’d have a small chamber where the bell siphons.
Making a bell siphon for aquaponics is not as easy as you might think. The first problem is that the shape of your tubing determines how much water will flow through it. You need to choose a shape that allows for more water flow than you need to run your system. If you are designing your own, you will have to calculate how much flow you need to run your system, and then design your tubing so that it can handle that flow.
The second problem is that the diameter of your tubing has to be chosen based on the amount of flow you want. If you have a garden hose with a 5/8″ diameter, you can’t run a garden hose with a 1/2″ diameter through it without clogging it up. There is a point where your tubing will have to get smaller than the size of the hole in which it is installed, and this will make it impossible to run a continuous stream of water.
How do I install a bell siphon for aquaponics?
If you have a bell siphon already, and want to add a bell siphon, you should be able to just follow these steps:
1. Take off the old siphon. (You can do this with a pair of pliers.)
2. Take off the top half of the old siphon. (This is the part that will go into your new bell siphon)
3. Make sure there is no water in the old siphon.
4. Make sure that the bell siphon has no holes or cracks in it.
5. Make sure that the bell siphon has a hole that fits perfectly into the bottom half of the old siphon.
6. Put the top half of the old siphon back on.
1. Place the new bell siphon over the hole in the bottom half of the old siphon.
2. Fill the bell siphon with water.
3. Put the top half of the old siphon back on.
4. Put the lid on the bell siphon.
5. Make sure there is no air inside the bell siphon. (Air will make the bell siphon not work.)
6. If you put a little dish soap in the water, it will help to clean out any water or sediment from the bell siphon.
7. If you use a lot of dish soap, it can get into the siphon. Then, it will stop the bell siphon from working.
8. If you do not want to use dish soap, just turn off the water in the kitchen sink and let the water sit in there overnight. The water will clear itself out.
9. Turn on the faucet and slowly turn on the water. (You may need to turn on the cold water first.) This will make sure that the bell siphon does not get clogged up.
10. When the water is at the right temperature, slowly start turning on the water to fill the bell siphon.
11. Wait until the water is full.
Which is better U siphon or bell siphon for aquaponics?
I have a 10 gallon tank with about 6 plants in it. I’m new to aquaponics and am wondering if I should get a bell siphon (which will be used for the water flow) or a u siphon (which will be used for my fish). I’ve looked at other aquaponics forums and most people are using a bell siphon but some are saying that a u siphon is better. What’s the difference between the two?
The bell siphon has a long neck that connects to the tank while the u siphon has a short neck that connects to the tank. The bell siphon is for the water flow, and the U siphon is for the fish. If you only have one of those, you will have to find some way to do both.
The answer depends on how you are going to use your system. If it’s just a hobby, then probably the U siphon will be fine. However, if you are looking at commercializing your system, I would go with the bell siphon as it allows you to add more fish.

Crawfish aquaponics is possible with the proper knowledge. Although we are more familiar with raising fish in aquaponics, other aquatic animals, such as crawfish, can also be included. You can easily raise crawfish alongside your aquaponics fish.
Although there can be some limitations to raising crawfish in aquaponics, you can work your way around it.
What Are Crawfish?
Crawfish are freshwater crustaceans. They belong to the group of organisms called Astacidea, which also contains lobsters. Crawfish are usually referred to as crayfish. Depending on the location, they can also be referred to as craydids, craybobs, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, bay bugs, or yabbies.
The word crayfish is more common in the northern parts of the Eastern United States, while crawdad is used in the central and southwestern regions. Crawfish is a term used farther south, although overlaps exist between the different regions.
Crawfish are commonly found in the USA, particularly in Mississippi through Louisiana as well as in different parts of the world.
How To Raise Crawfish In Aquaponics
Raising crawfish in your aquaponics will add a whole lot of diversity to your system. It is possible to raise crawfish alongside aquatic fish as they can live as good tank mates in your aquaponics system. However, there are things you need to put in place to prevent your fish from eating your crawfish.
Although not all types of fish will eat your crawfish, the fishes that might end up eating your crawfish are the omnivorous or carnivorous ones and the ones that are two to three times bigger than your crawfish. Also, note that almost all fish may try to eat baby crawfish. However, there are some things you can do to prevent this.
The good thing about crawfish is that they are bottom dwellers, unlike fishes that love swimming at the water’s top. Crawfish also love hiding places so that is an added advantage. This is why you have to create hiding spots for them in the fish tanks so they can avoid the fish. You can make use of big stones as hiding spots.
There is always a chance of fish-eating your crawfish. But don’t sweat it. Just try to follow the tips mentioned above to keep your crawfish safe.
Crawfish & Filtration
Although crawfish may help in terms of filtration, you will still need to get a filtering system as the plants in your system may not be able to take up nutrients, resulting in inefficient filtration sufficiently. The filtrating crawfish technique is not so superb. This is because as they are cleaning up your system by consuming this excess organic waste from fish, they are also producing their waste materials. Therefore, you will need to add a filtration system to clean your aquaponics system so the waste does not clog it up or cause your water quality to deteriorate.
Stocking Density Of Crawfish
Crawfish require a lot of space in aquaponics. As such, you can only raise a few of them in the system simultaneously. This is why it is not advised to raise only crawfish as the fish in an aquaponics system, as the few crawfish will not provide your plant with adequate nutrients. They should be raised with other fish so they both can produce enough nutrients for the plants.
As we mentioned earlier that crawfish are bottom dwellers. They are capable of taking over your fish tank which is why you need to raise a few of them. When a female crawfish can lay up to as many as 650 eggs at a time, this can cause a rapid increase in the population in your fish tank.
However, if you wish to sell them, you should help their survival by providing them with more hiding spots. This way, your fish will be limited from attacking the little crawfish and you can guarantee that you will have some for sale.
Crawfish Growing Requirements
Follow these crawfish growing requirements and enjoy a smooth crawfish aquaponics system:
Temperature:
Crawfish grow best in temperatures of around 70 to 75 degrees Fahrenheit.
pH:
They also prefer their water pH to be around 7.1 to 8.1. Other species of crawfish will do well with a pH of approximately 6.4 to 8.1. Therefore, make sure you are enlightened on the type of crawfish species you will be raising.
Ensure your filtering system cleans up excess ammonia and nitrite to a level your crawfish can handle. Ammonia and nitrite toxicity can reduce the survival chance of your crawfish. Therefore, always test the nitrite and ammonia concentration levels to make sure that they remain within the correct limits.
Maintain Low Stocking Densities of Crawfish:
Because crawfish require large spaces in the tank, try to maintain a reduced population. When they start producing offspring and their population gets high in the tank, try to take some out and divide them between tanks. You can sell the little offspring to a bait shop or fish store.
Crayfish need space to move around, so the ideal stocking density for them in a tank is 5 gallons of water per small crawfish. For larger ones, 15-20 gallons would be perfect.
Crawfish Feeding Habits
Knowing what to feed crawfish is very important if you are keeping them, mainly if you are farming them for commercial purposes. You need to provide them right so that they can grow optimally.
Crawfish are omnivores. They feed on snails, insect larvae, worms, and amphibian tadpoles; some eat vegetation. So they will help you hunt worms, snails, leeches, etc you might have in your system.
Crawfish don’t usually go out to search for food. They make do with what they have around them. Therefore, there’s no worry about them eating your little fish.
How to Raise Crawfish in a Pond
If crawfish are raised in a pond, they need to be located in areas that are flat and open. The soils in these areas should be full of clay. An adequate supply of water is also essential for raising crawfish in a pond. You might need to perform regular water changes to maintain excellent water quality for your crawfish growth.
With regards to soil types, clay loam, and silty clay loams are suitable types for crawfish ponds. The clay is necessary to maintain the structure and integrity of the burrows that crawfish make, as well as important to hold water.
How to Raise Crayfish in Aquaponics
Raising crayfish in tanks may not be common, but it is absolutely possible. Here are the crucial factors to consider if you want to run a successful crayfish aquaponics system.
Maintain the correct stocking density of 5 gallons of water per small crayfish and at least 15 gallons per large crayfish.
Keep the temperature of the water in which they are kept between 70 and 75 degrees Fahrenheit.
Do not expose them to direct sunlight. Crayfish do not require light in their environment. So make provide them with either shade or suitable hiding spaces in their tanks.
The ideal pH for crayfish in aquaponics is between 7.2 and 8.2. Maintain it at this range for your fish to thrive.
Make sure that the dissolved oxygen levels in the water never drop below two parts per million.
Feed crayfish a varied diet that includes mussels, worms, snails, and some vegetation. Feed them only one to two times a day. This should be enough for them. It will also help keep your water quality good.
Clean crayfish tanks at least once a week to limit the buildup of waste from uneaten feed and feces. This will further help to maintain good water quality in your system.
Suitable plants for crayfish include peas, celery, and herbs such as dill and marjoram. Pair your crayfish with these plants and you will have a tremendous and well-functioning aquaponics system.
Closing Remarks On Raising Crawfish
Raising crawfish in aquaponics may not be common but it is an exciting venture that a lot of people are currently trying their hand at. It will become more popular shortly as aquaponics farmers learn more about them and how to optimize their growth and production.
If you would like to try your hand at this exciting farming method, you can use this article as a guide, and be well on your way to success. Happy farming!
FAQ’s
Can you do aquaponics with crayfish?
The answer is yes. The crayfish will eat the algae, which in turn will give off oxygen and the bacteria that help break down the waste. And then the crayfish will eat the fish food, which will give off more oxygen and the bacteria that break down the waste. There are a few things to consider before you jump right in and start your own crayfish aquaponics system, though. Crayfish do not like to live in the same tank as other animals, so if you have a small aquarium, you should only put one or two crayfish in it.
If you have a larger tank, however, you can house more crayfish. The crayfish also need to be fed regularly, as they are omnivores. You will want to feed them a mixture of algae, fruit flies, and fish food. It is best to keep the crayfish in a separate tank from your fish, as crayfish are known to eat fish and even each other. This means that you will need to get two tanks – one for the crayfish, and one for your fish. If you are new to aquaponics, you may also want to invest in a water conditioner.
A water conditioner will help to remove excess nutrients from the water so that you do not need to add as much fertilizer. They are also helpful for keeping your water clean and clear. Aquaponics is becoming increasingly popular as people look for ways to improve their lives without relying on traditional methods. While there is still plenty of room for improvement, aquaponics is a system that has many benefits.I am a photographer. I’m working on an album right now with some very important people, and they have been giving me great advice.
How big should the tank be?
The tank can be either bigger or smaller than the grow bed. If you want a small aquarium, it can be as small as a 5 gallon or as large as a 55 gallon. You will want to consider the size of your fish. A very small tank won’t hold much water and won’t allow your crayfish to swim around.
If you are going to keep crayfish, you will need a tank that is at least 10 gallons, but larger would be better. As for the lights, a plant light is usually not strong enough for plants and fish. I use a couple of 10 watt aquarium bulbs for my aquariums. If you are going to use a submersible pump, make sure it has a good enough power supply to run it. I have used aquarium submersibles that cost about $40. You don’t need a lot of lighting though, as long as it’s bright enough for the plants and the crayfish. I use 3 aquarium bulbs for my lighting.
Can you feed crayfish to your fish in aquaponics?
In aquaponics, crayfish are used as a food source for fish and other aquatic animals. Crayfish can be used as fertilizer by adding them to the tank or pond.

Catfish aquaponics has been on the rise in recent years. If you are struggling to know how many catfish per gallon of water to stock in your system, do not worry. This article will answer this question for you, and address many more.
The delicious catfish is one of the most rewarding fish you can raise in your aquaponics system. They are pretty forgiving and tolerant and they can survive in a wide variety of water conditions.
Knowing the stocking density of catfish will increase your chances of a better and more rewarding relationship between your plants and fish. So let’s dive into how many catfish can fit per gallon of water.
How Many Catfish Can Fit per Gallon of Water in Aquaponics?
Getting the correct stocking density for your catfish will help to go a long way in your aquaponics.
If the fish stocking density in your aquaponics system is low, there may not be enough nutrients to support the plant biomass. Conversely, if you have too many catfish, the filtration system (bacteria, plants, etc.) will not be able to adequately clean the impurities in the system and it may crash. This may in turn cause your catfish due to excess ammonia, and other critical water quality parameters to be out of the ideal range for catfish growth and health.
The appropriate number of catfish you can fit per gallon of water is one pound of fish per eight gallons of water. This way, stress is reduced and there’s adequate space for oxygen. However, note that when it comes to a fully grown catfish, you will require more than 8 gallons of water per fish.
Catfish are fast-growing fish and they usually grow quickly during their younger years. You can increase the quantity of water as your aquaponics system duration increases and the nitrifying bacteria get established.
When it comes to catfish aquaponics recommended tank size, depends on the size of your fish. Catfish are fast growers and can grow up to 2 or 3 pounds in 12 months.
The fact that a whole 8 gallons of water are required for just one small-size catfish shows a large tank is required. Although, if you wish to raise one or two catfish and a small grow bed, you can make use of a small tank.
Go for a bigger tank so you can give your catfish a good quantity of filtration, aeration, and water flow and your catfish will flourish excellently.
Let’s take an illustration and see the ratio of a large tank to the number of catfish:
Let’s take 6 fully grown catfish weighing 2 to 3 pounds each. The total weight of all 6 grown catfish will be approximately 18 pounds. Therefore, a total of 18 pounds of catfish will require at least 144 gallons of water. (Using one pound of catfish should have 8 gallons of water).
Other Catfish Requirements
The tolerance and hardiness of catfish vary with species. Therefore, select the variety of fish that will suit and adapt to your aquaponics system.
Among the different species of catfish, channel catfish is one of the best varieties, the reason being that they are very forgiving and tolerant to cold water. They are perfect for beginners and they can as well live with other fish such as koi, tilapia, and crappie.
Other water quality requirements for your catfish to flourish in hydroponics include:
Dissolved oxygen: good air circulation and aeration is needed for your catfish. Ensure you use good air stones and air pumps so there is adequate availability of oxygen to suit your catfish. One amazing quality of catfish is that they can breathe air! This means that even if your air pump stops working, your catfish will not die because they will swim to the surface and breathe atmospheric oxygen. They will survive until you can come and fix the air pump and peace will be restored.
Food: feed your catfish with good high-quality protein fish food. You can also feed them with worms, black soldier flies, and insects. Ideally, we recommend you supply your catfish with about 2.5% of their body weight. Even though you can’t weigh your catfish weigh all your catfish, you can estimate their body weight from their sizes. A full-grown catfish weighs around 2 to 3 pounds. If there’s uneaten or excess food in your aquaponics system, you will need to readjust the amount of food the next time you feed your catfish. This will help to avoid waste and contaminating the system.

Temperature and pH: catfish can withstand a variety of water temperatures. However, the ideal water temperature ranges from 65 to 90 degrees Fahrenheit. If the temperature goes above or below these standards, your fish will not grow optimally. You will need to stop feeding your fish (to minimize stress on the fish) until you can find a way to get the temperatures just right. They also have good tolerance to pH levels. Their pH can range from 7 to 8.
How Many Catfish in a Tank?
Generally, the rule for the calculation of how many fish can go into a tank is 1 inch of fish per gallon of fish. 10 percent of the water should be replaced with gravel where the fish can find a good hiding spot.
For example, a channel catfish tank size needs 8 gallons of water per fish. This means that you will need a large tank for bigger or more fish that you want to keep.
How Many Gallons Does a Catfish Need?
15 pounds of catfish require about 120 gallons of water.
What Are The Best Catfish For Aquaponics?
Several different species of catfish can be used in aquaponics, with each having its advantages and disadvantages. This allows you to select the one that best suits your needs and your system setup.
According to the Food and Agriculture Organization, the three best catfish that are grown commercially and grow best in aquaponics are Channel catfish (Ictalurus punctatus), African catfish (Clarias gariepinus) and the Brown bullhead catfish (Ameiurus nebulosus). Let us go into a bit more detail about these three aquaponics catfish.
1. Channel Catfish
Channel catfish can be stocked in high densities because they have a high tolerance for sibling densities. They are tolerant of cold water but grow faster at higher temperatures. Another advantage of using catfish in aquaponics is that they can live with other fish such as crappie, tilapia, and koi. So if you want to do a polyculture, it is the best candidate.
Channel catfish is one of the fastest-growing catfish and will grow very fast in your aquaponics system. They can attain growth rates of 3 pounds in just 12 months. This will ensure that you have a constant supply of plenty of fish to keep your system operating optimally.
2. African Catfish
The African catfish is another catfish species that is highly tolerant of sibling density. These fish can be stocked at high density and their growth will not be compromised. These fish can also tolerate a wide range of temperatures but grows best at higher temperatures.
African catfish are air-breathing. They are a great candidate for aquaponics systems because they can tolerate low dissolved oxygen levels in the water, so in the case where there is a power outage or something that results in a drop in the oxygen levels, your fish will survive for hours in those conditions. Even if a fish happens to jump out of a tank, the fish can survive until you can put it back in the water.
African catfish are very hardy fish and can withstand a wide variety of environmental conditions such as high ammonia. Growing this fish in your system will have low rates of mortalities.
A full-grown African catfish will reach a weight of 20 kg. This is provided that the ideal conditions are provided. It can grow up to 2 pounds in a space of 10 months. If the temperature of the water drops below 68 degrees F, the fish will stop growing so you will need to ensure that the temperature never drops below this.
3. Brown Bullhead Catfish
The Brown bullhead catfish can also be grown in aquaponics, although it does not grow as fast as the others. It also can survive some periods with no aeration in the water as long as the stocking density is kept low and the water in the tank is shallow.
These fish are benthic omnivores. They feed on insects, plants, worms, crayfish, and food pellets. Temperatures of 78 – 82 degrees Fahrenheit are ideal for these fish, and at this range, they will grow up to 1.10 pounds in two years.
Final Say – Catfish Aquaponics
Catfish are great fish to keep in an aquaponics system. These fish are heavy feeders, meaning they will provide sufficient waste that will be used as nutrients for your plants. They are also highly tolerant of sibling density, meaning that you can stock a lot of them in a single tank and they will continue to grow well. This limits the number of tanks that you will need for your system.
Tilapia used to be the most common fish grown in aquaponics, but catfish is also a good candidate. Whether you are a novice or an experienced fish culturist, the catfish is a good fish to try.

When it comes to hydroponics, learning how to use pH up and down is essential to maintaining healthy plants throughout their growing process.
The pH is one of the most important aspects to consider when growing your plants. It can be used to determine the overall health of the plants. If your water has a high pH, it can mean that you are having trouble keeping your roots healthy.
There are many reasons why your pH may be off. Your tap water could have a higher pH than normal, which is due to the alkalinity of the water.
What Does pH Mean?
pH is a measure of acidity or alkalinity in an aqueous solution and can be expressed as a number from 0 to 14. A pH between 7 and 8 is considered neutral (or neither acidic nor alkaline). The lower the pH, the more acidic the solution is, and the higher the pH, the more alkaline the solution is.
In hydroponics, you want your nutrient solution to be around 5 or 6 pH. Your plants need the proper balance of nutrients and minerals to grow optimally. If the pH is too high or too low, it can lead to nutrient deficiencies and disease.
How Do pH Up And Down In Hydroponics?
1. Buying pH Up and Down
Many gardening stores and online retailers sell a product called pH Up and Down. It features two bottles of liquid, one for increasing pH levels and one for decreasing pH levels. This product allows you to adjust the pH levels for your plants by adding base or acid.
After testing your water or soil, you can add either a small amount of base or acid. Add just one drop at a time before you achieve your desired pH levels. Be sure to thoroughly read the instructions before using.
2. The easiest way is to use a pH meter
A pH meter is an easy-to-use, inexpensive tool that helps you determine the exact pH of your nutrient solution. You simply add the meter to the water or soil you are testing and follow the instructions on the label. The meter will tell you the exact pH of the solution.
You can find pH meters online, in superstores, and in most gardening centers. They are generally easy to use and efficient.
3. Another option is to use an inexpensive aquarium pH controller
These are available in stores or online. They are easy to use and work well for small systems. They come with a built-in pH meter. They not only monitor but also control the pH level of water.
You will need to calibrate them every once in a while. You can do this by adding some water with a known pH to the tank and then adding the controller.
4. Another option is to use a soil pH indicator
These are available at most garden centers or online. They are very cheap and work well for small systems. It works by inserting a small strips into the solution.
The strip will then indicate the pH level of your soil. The colors of the strip will indicate the pH level of your soil after testing.
5. An even better option is to use an auto-pH controller
An auto-pH controller is an automated pH correction system that automatically monitors and adjusts the pH in your solution. These controllers can be purchased from most hydroponic supply stores. They are very easy to use, require no maintenance, and will make sure you have a perfect pH in your solution every time.

How Do I Keep My Hydroponic Plants Happy?
Keep your plants healthy with proper nutrition. Make sure you use a balanced fertilizer that has all the nutrients your plants need. Use a good-quality liquid fertilizer that will not contain any harmful chemicals. The best way to ensure that your plants get the nutrients they need is to use a nutrient solution that has all the required nutrients in the proper balance.
One of the most important parts of keeping your plants healthy is to make sure they have enough light. If you are using a grow light, be sure to adjust it so that it shines on the plants evenly. Many types of plants need direct, full light to grow at their maximum rate.
It is also important to keep the hydroponic water temperature for your plants at 65 to 80°F. If you are growing indoors, make sure that your lights are set on a timer so that the lights turn off and on automatically each day.
Keep your plants healthy by adding fresh air. Make sure to open the windows in your grow room as often as possible to provide plenty of fresh air. If possible, most plants will also benefit from a few hours outside every day.
In Summary – pH Up And Down
The ph up and down in hydroponics as we have learned above is essential for the growth of these plants. Hydroponics being a sensitive method to grow plants fast requires the proper growing conditions otherwise the plants will fail.
