LED Grow Lamps Can Generate Less Heat
February 6, 2019
When you are growing plants that need a more concentrated delivery of light (such as seedlings), the closer you can place your lights without burning them, the better. Smaller LEDs generate less heat than other grow lamps and can be placed closer to your plants. Lower heat output with heat emitting from the back of the fixture means less heat directed to the canopy of your plants.
But keep in mind that larger LED rigs can still generate heat, especially in enclosed growing spaces.
