FAQ’s

Can I use T12 as grow lights?

T12's are not really meant to be used as grow lights. They are not designed for that purpose, and are not as efficient as other lighting technologies.

They are intended to be used as a general lighting fixture in the home, similar to an incandescent bulb. The average T12 has a rated output of about 700-1000 lumens (lm). For comparison, a 600W incandescent bulb has an output of about 30 lm. If you were to use a T12 as a grow light, you would have to replace it every year or two because the light output will decrease over time due to a chemical reaction.

Can I use a regular fluorescent light as a grow light?

Yes, you can.
Fluorescent bulbs are the most common type of lighting used in homes and offices today. They are compact, low energy consuming, durable, and easy to operate. They can be found at any hardware store or home improvement store. You can choose between incandescent and fluorescent bulbs for your grow room.
The only issue you will have with using a regular fluorescents is that the light will not be as bright as it could be. You can still use a regular fluorescent bulb for plants if you are growing indoors. The amount of light that your plants get depends on how close they are to the bulb.

Which is better for plants LED or fluorescent?

LEDs are superior for plant lighting, but they're not perfect. They don't have the same color temperature (which you may want in your garden) as florescent tubes, and they aren't quite as efficient. The problem is that LEDs are based on semiconductors, which can be easily damaged by moisture, so you'll need to keep them well-ventilated.

LEDs can also be pricey, so it may be worth considering a florescent tube instead of an LED if your budget allows.

Can I leave my grow light on 24 hours?

Yes, you can leave your grow light on 24/7 and it will not damage your plants. But, there are a few things you should be aware of if you do so. The first thing is that you need to make sure you have a good ventilation system in place to avoid a buildup of carbon dioxide. If the carbon dioxide levels get too high, you could end up with a greenhouse effect. This could cause your plants to look like they are under stress and could even kill them. Also, make sure you have adequate humidity levels in your closet, as well as a temperature monitor. These will help you keep track of how much heat your grow light is giving off and how much humidity you’re creating.

What light bulb is closest to natural sunlight?

I think the closest you're going to get is a "daylight" bulb. There are bulbs that are closer, but they are still far from perfect. This one is rated at 2700K and has a color rendering index (CRI) of 92, which is very good for a bulb in this range.
