If you don’t have a grow light, you can use a CFL or LED light. LED lights are more energy efficient than incandescent bulbs, but they’re not as bright as a full-spectrum fluorescent bulb. They’re also more expensive, and you’ll need to buy extra bulbs to power them, which can add up to a few hundred dollars over the course of a year.

Can you leave grow lights on 24 hours a day?
You shouldn’t leave grow lights on 24/7. Plants need a light-dark cycle to grow. During periods of darkness, it’s believed that they use this time to move vitamins and minerals into their bodies. 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. You can also check to see if your plant is ready by looking at its leaves. They should be soft and pliable, not stiff and brittle. This is a good sign that the plant will be able to withstand the rigors of a transplant.
Can plants get too much artificial light?
Most plants do well with 12-16 hours of artificial fluorescent light a day. Too little light will cause a plant to be spindly, too much light will cause a plant to be dry and brittle, and leaves will fall off. Light is the most important factor in determining the health of a houseplant.
The amount of light your plant receives will determine how long it will live. Light intensity is measured in watts per square foot (W/sq.ft.). For example, a 100 watt light bulb will produce 100,000 lumens (lumens are the units of measurement used to measure light intensity).
If your plants are in a room with a ceiling height of 10 feet, they will receive a total of 100 watts. This means that if you put a 10 foot ceiling in the room, your lights will only be able to reach the top of the ceiling, not the bottom. You will also need to consider the type of lighting you are using.
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.
Are purple or white grow lights better?
LED fixtures create a more pleasant environment, and the spectrum is similarly useful to plants as purple light, but fixtures are more expensive. In the end, it’s up to you to decide what’s best for you and your plants.
If you’re looking for something that’s easy to install and doesn’t require a lot of maintenance, you might want to consider a fluorescent fixture.
On the other hand, if you don’t have the time or money to invest in a high-end fixture, or you just want a simple, low-maintenance fixture that will last a long time, a CFL is the way to go.
When should I turn my grow lights off?
The only time you should not use lights on your plants is when they are outside. They should be under the lights if they are inside the house. When you are ready to plant them indoors, you can turn off the lights while your seedlings are outside, and then turn them back on when you are done.
Do plants grow faster with 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 would if they were exposed to the same amount of light.
The study, published in the Proceedings of the National Academy of Sciences (PNAS), found that exposure to light at different times of day can have a significant effect on the timing of flowering in plants.
The results suggest that plants may be able to adjust their flowering schedule in response to changes in light levels.
