:evilgrin0031:Turn that sucker horizontal & fit a good footprint reflector over it. If it's a 600W run the damn thing down until you are too close, then back it off a few inches. Or keep it close but run a fan over it. If its a 1000, be very careful. It can burn up foliage quick.
You'll need to check often, as post flip stretch means it will grow too close. Amazing how much & how fast with some strains. Too little light, it might stretch too much & they will be calling you "Larfy Larry" behind your back.
:sunToo much light is a bad thing too. Haven't gotten there myself, but I've heard it's not good! Air temp & humidity are now both critical too. 69 nite, 79 day, 55% is ideal, but some strains are happy in a wide range, some aren't.
:damnhippie:Or always grow Top44 or NL or the E-Z stuff. If you do everything dead wrong, then they only give you good results. lol! Or grow Haze. If you sneeze, your whole crop dies! I just popped 25 pale tannish Original Haze beans into my seed starter, so wish me luck. I'm gonna need it, I would bet. I do have the Chemo, which Tabor told me is "The Sativa Tamer". Maybe by the time these are ready, I can have my hillbilly breeding program figured out. It's a goal, but it's a lot to learn. Trial & error is fine, but I may need some major help on this one.
