Usually start freshly cracked seedlings under my big cfl,but I broke that shit yesterday, and cannot gt another now. Have them under a 500 watt mh (1000w dimmed 50%) at 4' away, super far. I'm keeping temps 74-77f and rh is a little low for now 40% or so.
will using the hid hurt my seedlings. Is it the light intensity that can harm seedlings? Or excessive heat usually caused by it? Because my temps are good, right?
