Heat Generated by Grow Lamps
December 4, 2018
Some lamps generate more light or more heat than others. Fluorescent lamps, CFLs, and LEDs are typically the easiest options for starting young seedlings, as they generate lower levels of heat than HID lamps and you can place them closer to your tiny plants.
If you site an HPS lamp a few inches away from young seedlings, the intense light and heat will quickly fry them. Once your seedlings grow up, you can employ more intense types of lighting.
