if you can feel the heat, about 6 inches away form that, maybe more for seedlings. maybe I need to pull my seedlings away from my light....(goes and checks seedlings)!!!how close is to close? lol
That is unnecessary IMO and someone risky but if it works for you then right on! i like to stretch my seeds a little to build their stalk so it really is personal preferenceView attachment 1815806View attachment 1815805
Idk, i'm gonna have to disagree with the recommendations of backing off the lights. As you can see, I run mine at an inch, or less, without any issues at all. I bring my lights down as soon as the first leaves unfold, and they love it.
