Are LED Grow Lights worth it?
LED grow lights are great because they are energy-efficient, durable, and have ‘tuned’ light spectrums to best meet the plant’s needs. However, there are still many excellent fluorescent grow lights that are much cheaper and still contribute to wonderful plant growth.
Should seedlings get 24 hours of light?
Yes, it is true that your seedlings need lots of bright light to grow healthy and strong—but they also need a period of darkness in order to thrive. … These fluorescent lights should be left on for 12 to 16 hours a day. Many people make the mistake of leaving their seedlings under fluorescent lighting 24 hours a day.
Do plants grow faster under 24 hours of light?

Why are grow lights purple?

Can you leave grow lights on 24 hours a day for vegetables?

Can plants get too much artificial light?
Plants cannot get too much light, but they can get too much of the heat energy that comes with the light. Photosynthesis and other plant growth processes will shut down when the environmental and tissue temperature gets high enough that all the water taken up by the plant is used to cool the plant tissue.
Can tomatoes get too much light?
Too much sun may cause the soil to lose water quickly through evaporation, even if temperatures aren’t too high. The plant foliage begins to wilt and fruit may stop forming or drop from the plant. Water stress can also lead to blossom-end rot, where the bottoms of the tomato fruits become discolored and sunken.
Can LED grow lights burn plants?
While LED lights do produce some heat, they deal with that heat more effectively than other light types. Plants can grow much closer to LEDs than other lighting types because of this. Usually crops can grow right up to the light without burning.
