Thought I'd also go ahead and give a brief breakdown of what I'm running..
CoolGrows 3x3x6 tent
Vivosun 600w MH/HPS conversion air-cooled good and ballast
Vivosun 6" inline ventilation kit w/carbon filter(not currently in use)
1x Crossfire Hurricane from The Bank Genetics
4x Green Crack hybrid(I was gonna call it Midwest Crack but I think I like GCX better)
Pro-Mix Ultimate Organic mix
amended with perlite, vermiculite, worm castings, bone meal, diatomaceous earth and Burpee Natural & Organic starter+transplanting with mycorrhizae
And these,
