about 18" away, a bit further than i like but the plants dont seem to be stretching too much, even if they do there's a fan blowing constantly to build the stalks up.
!!!!!!! NEWBIE !!!!!!! Question When can i start using my 6ooW dual spectrum HPS? If i can start now. How far away should the lamp be? My seedlings are under CFL's and are a week old.
Cheers
