Can LED grow lights burn plants? 420 Guide for Beginners
Many LEDs work best when kept around 18" or more from the top of the plant, but it’s important to ask the manufacturer about the specific LED grow light model since each one is different from each other. The size of the LED bulbs, the way the lenses are made, and the angle the lamp directs light downward all make a big difference on how far your cannabis plants need to be without experiencing “sun burn” from full spectrum led grow lights.
LED grow lights for marijuana can burn your plants even in comfortable temperatures!
Most common things you should pay attention to when using LED grow lights
Setting the Lamps at an Improper Distance
Overheating or insufficient lighting can result from having too many or not enough lights, but it can also result from placing the lights too close or too far from the plants. 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.

OVERLAPPING LIGHTS
In larger grows where there are many lights in the same room along with reflective walls, it is often more effective to puts the lights higher so that the is overlap between many lights. This means that each plant will get light from many angles and this will promote much better penetration into the canopy and better overall yield.

Using the Wrong Light Schedule
You should be careful not to leave the lights on all the time, or worse, the opposite — forget to turn them on. It might sound trivial but it’s quite easy to mess up the light schedule and even a minor change might have a negative impact the plant’s growth. Cannabis needs about 18–24 hours of light during the vegetative stage and 12 hours of light during the flowering stage.
