I have an area approx. 9 x 5 x 8 tall. I'm running two air cooled 430 hps and a 250 hps (not air cooled). I'm currently trying 2 2x2 scrog in pro mix, 2 fim'd in pro mix and3 in an 18 gal bubble bucket. I figured i'd just try them all and see what works the best. I expecting some new genetics soon and i don't want to mess them up. Lemme know.
