Some gardeners like to leave their lights on for 24 hours to get maximum growth. However, by far the most popular light duration for vegetative plants is 18 hours on and 6 hours off. This schedule will mimic a day of full sunshine followed by a natural dark period.

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.
How long should grow lights be left on?
To be effective, grow lights really need to be on for at least 8-10 hours a day. This can vary up to 16 hours, depending on the conditions. That’s why LED grow lights are so popular – when they have to be left on all day, it’s best to use an energy efficient type! Always position a grow light above the 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.
Can you overuse a grow light?
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 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.
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 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.
Do plants grow faster under 24 hours of light?
Exposure to 24-hour light helps some plants like orchids (Orchidaceae spp.) and cacti (Cactaceae spp.) bloom more quickly than they normally would if grown outdoors.
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.
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.
How far from plants should LED grow lights be?
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.
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 survive with LED light?
CFL bulbs promote longer-lasting life hours and a better light spectrum for growing. Offering low energy usage, low heat, and color optimized for growth, LED lights are the most efficient, effective, and customer-friendly way to grow plants at home than growing with fluorescent lights or incandescent 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.
