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.

How many hours a day should my grow lights be on?
Most plants require grow lights to be on 12 – 18 hours per day. However, the duration varies greatly, depending on whether the plant is shade tolerant, and grow light factors (light intensity, light quality, distance from plant).
Should I leave my grow lights on all the time?
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.
How long do you keep plants under grow lights?
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.
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.
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 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 overuse grow lights?
While leaving growing lights on for a single night is unlikely to have long-term effects on your plants, constantly leaving the lights on can stunt their growth, prevent flowering, cause wilting and burn damage, and may kill the plants.
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.
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.
What plants benefit from grow lights?
With a set of grow lights, you can grow many plants indoors, including houseplants, orchids, and even some fruit and vegetable crops. Grow lights are ideal for seed starting because they help ensure stocky, green seedlings. A wintertime harvest of herbs and salad greens can also be grown under lights.
Do grow lights count as direct sunlight?
But many grow lights are now made specifically to cover the full spectrum. As a result, full spectrum grow lights are almost as good as sunlight! But even if you do have windows, they filter out a lot of the intensity of the sun. So, it’s not as powerful as direct light from the sun or a grow light.
How much power does a 1000W LED grow light use?
1000W powerful lights: double chips 5W double chips LEDs which is much brighter and efficient than 1W and 3W LEDs. Energy saving, just consumes about 110w-120w power. High brightness and long lifespan.
How much does a 600 watt grow light cost to run?
The cost to run the lights per day is $0.2735236 or $8.20 per month. If I have an HID (high intensity discharge) light with a 600 watt bulb in it, using the same method of calculation, it would cost me $30.90 per month. Of course, with a metal halide HID light I could grow my own tomatoes and other vegetables indoors.
