In general, you’ll want to ensure that your seedlings get at least 16 to 18 hours a day of light, or even 20-22 hours per day if you have a low- or medium-intensity grow light. The 16 – 18 hours of grow light per day is a general guideline.

How many hours a day should my grow lights be on?
How Long Should a Plant Grow Light Be Left On? As a general rule of thumb, most vegetables and flowering plants need 12 to 16 hours of light per day, with flowering plants at the top end of that range. Plan on giving most plants at least 8 hours of darkness per day.
How long should hydroponic light be on?
You should plan your system on having at least 14 to 16 hours of bright artificial light, followed by 10 to 12 hours of darkness every day. The darkness is just as important as the light—just like animals, plants need time to rest and metabolize.
Can grow lights be on 24 hours a day?
A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
Can plants get too much artificial light?
Duration of Light Most houseplants do well with 12-16 hours of artificial fluorescent light each day. Too little light will result in elongated, spindly growth and too much light will cause a plant to wilt, color to fade, soil to become excessively dry and foliage to burn.
How far should LED grow lights be from plants?
There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
Do grow lights use a lot of electricity?
Grow lights don’t use as much electricity as you may think. However, since most grow lights are so energy efficient, you are getting huge amounts of light (and growing power) for your money! Make sure your grow room’s power circuit can handle the power draw.
How long should you keep the grow lights on plants?
Most plants need a grow light on for at least half of the day, so about 12 – 14 hours. However, some plants need more than that, and the light intensity and light quality vary greatly between grow lights.
How often should you water plants under grow lights?
Check water daily. Seedlings should be moist, but not soggy. Overwatering is the number one killer of plants.
How do you know if your plant is getting too much light?
If your plant is not getting enough light, the most common sign is the yellowing and dropping of leaves, stunted leaf growth, elongated stems, and a dull-green color. If your plant is getting too much light, then its leaves will have singed tips, burned patches, or will be falling off (yikes!).
Can you leave grow lights on 24 hours a day tomatoes?
Scientists have found a gene in wild tomatoes that enables farmed tomato plants to be grown 24 hours a day under natural and artificial light, boosting yields by up to 20 per cent.
Can you leave LED lights on 24 7?
To put it simply, well-manufactured LED lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, LEDs produce minimal amounts of heat, which means they are unlikely to overheat or set on fire.
Can plants recover from too much sun?
The short answer is yes it can. Typically, a plant or tree isn’t going to be immediately killed when receiving too much sun, but, it will be a gradual process over a few days or weeks. A lot of times there are identifiable symptoms of sun stress that can help a gardener prevent death.
Can plants get too much water?
Overwatering, in simple terms, drowns your plant. Healthy soil allows for oxygen to exist in the space between particles of soil. If there is too much water or the soil is constantly wet, there is not enough air pockets. This results in a limited oxygen supply and plants are not able to breathe.
What happens if a plant gets 24 hours of light?
The Dark Side of Photosynthesis During light reaction, the plant absorbs light and turns it into energy. Because dark reactions do not require the absence of light, plants will remain healthy when exposed to light 24 hours a day. There are some plants, however, that will survive but not thrive without darkness.
