Well I guess sense i've been lurking around this fine site gathering as much info. as I can before I start my Cabinet grow. I figured I might as well register and say Hello. I'm a long time medical marijuana patient (at least one good thing about living in California....that and the weather.....oh and the women, OK so this place isn't that bad)lol. A little info on my cabinet (i'm still in the planning and purchasing phase), it's a old military locker that measures 6'height X 3'wide X 26"deep. I plan on going with a passive air intake, a 4" S&P mixvent fan for exhaust, with a 400watt HPS in a cool tube with a inline 4" fan. Everything else is still up in the air but hopefully with a bit more research I'll get everything ironed out. Oh by the way I'm a electrician so if you got any electrical questions I might be able to help you out. LD
