When they are outside, you should not use lights on your plants. They should be under the lights if they are inside the house. If you’re in the process of hardening them, you can turn off the lights while your plants are outside.
You can put them in a plastic bag and leave them outside for a couple of days. This will keep the light from shining on them and they will be protected from the sun.

How many hours a day should a grow light be on?
Grow lights need to be on for at least 10 hours a day to be effective. Depending on the conditions, this can be as long as 16 hours. It’s best to use an energy efficient type of grow lights when they have to be left on all day.
If you want the light to be overhead, position the grow light above the plant. If you’re growing indoors, you’ll want to make sure that you have a good ventilation system in place. The fan will draw air in from the outside, which will help to keep the temperature of your grow room at a comfortable level.
If you don’t have an air conditioner in your room, then you can also use a humidifier to help with the humidity. Humidifiers can be purchased at most home improvement stores, and they will work just as well for indoor growing as they do for outdoor growing.
Can I leave my grow light on 24 hours?
You shouldn’t leave grow lights on all the time. Plants need a light-dark cycle to grow. It’s believed that they take care of the rest of their needs while resting during periods of darkness, and that they use this time to move nutrition into their limbs. If your plants look like they’re ready for transplanting, then you’re good to go.
If they don’t look ready, it’s probably best to wait until the next growing season to transplant them. This is especially true if you plan to grow more than one plant at a time, as you’ll need to make sure that all of your transplants are grown in the same location.
Can you leave a grow light on too long?
Some growing lightbulbs give off heat, so if a lamp is on too long, or is set too close, it can burn the plant’s leaves. If your plant is showing signs of stress, it might be getting too much light.
If you’re growing a lot of plants in a small space, you might want to consider using a fluorescent light bulb instead of a regular incandescent bulb. Fluorescent bulbs are more efficient and last longer than regular bulbs. They’re also more energy-efficient, which means you’ll save money on your electricity bill.
Do plant grow lights use a lot of electricity?
It depends on the size of your grow space. If you only have one plant, you will only need 30 to 40 watt of power. If you are growing a lot of plants in a small space, then you may need more power than you think.
For example, a 30-watt grow light may not be enough to power your entire grow room. If you want to grow more than a few plants at a time, it may be necessary to buy a larger power supply.
Can LED grow lights burn plants?
The reality is that modern LED grow lights can produce a very high level of light and it can cause photo-bleaching and burn leaves. This depends on the plant, but a PPFD of 800 is enough to cause the leaves to turn brown. If you have a plant that is very sensitive to light, you may want to consider a different grow light.
The answer to this question depends on a number of factors, including the type of plant you are growing, the size of your grow space, and how much light you need. For example, if you’re growing a large plant in a small space (like a greenhouse), you’ll need more light to grow the same amount of plants.
On the other hand, a smaller plant will need less light than a larger plant. The best way to find out is to experiment with different types of lights and see which one produces the best results for your particular situation.
Do plants need darkness to grow?
Plants, shrubs and trees use sunlight during the daytime, but at night they need darkness to regenerate a key compound. Nighttime lighting can affect the ability of vegetation to create this compound.
The study, published in the Journal of Experimental Botany, found that when plants were exposed to artificial night-time light, their photosynthetic activity was reduced by as much as 50 per cent. The researchers this is the first time this has been shown to occur in a plant species.
What color grow light is best?
Blue light at the higher end of the spectrum is best for photosynthesis, while violet-blue light at the 400 nanometer range is best for plant growth. The amount of light you need to grow plants depends on the type of plant you are growing.
For example, if you grow tomatoes, you will need more light than a tomato plant that is grown for its fruit. In general, a plant will grow faster if it receives more sunlight than it needs.
How much grow light do indoor plants need?
plants. At least six hours of darkness each day is essential to the health of your plants, so don’t be tempted to leave the lights on 24/7. Light intensity is measured in watts per square meter (W/m2).
If you’re growing plants indoors, you’ll want to choose a light source that produces the same amount of lumens as your plant requires.
How much faster do plants grow with grow lights?
Those who grow with a 24 hour grow light may reach the end of the bloom cycle 20% quicker than those who give up the light. “I think it’s a little bit of a chicken-and-egg thing,” Chourey said. “If you’re going to grow indoors, you have to have a light source.
Do plants need to rest at night?
I posed the question to several plant experts and the short answer is no, at least not in the sense. Plants don’t seem to have central nervous systems that are important in sleep. Instead, sleep is a state in which the body is in a deep state of rest and relaxation.
“Sleep is not the same thing as REM sleep, which is when the brain is active during the day,” said Dr. Michael J. Gazzaniga, a professor of neurology at the University of California, San Francisco, and a sleep expert. “It’s a different kind of sleep that occurs when you’re asleep. It’s called non-rapid eye movement (NREM) sleep and it’s characterized by slow eye movements, deep breathing and deep muscle relaxation, all of which are signs of deep relaxation and restfulness.”
In other words, plants aren’t sleeping. And that’s what makes them so fascinating.
