my bad. i miss read your box dimensions. you'd have 12 sq ft if you go 6' x 2'. 1 plant per 2 sq feet would be good. you could bet by with 1 per sq foot if you don't let em get too big.

yes on the sq ft to lumens question. however if your plants are only taking up 1/4 of your space and you only have lights over them you need something to block off the rest of the cab or you're gonna be loosing a bunch of lumens. and even then, when using the entire space the amount of CFLs needed and othe equpment for the CFLs you mine as well have bought the HPS.

i'm just telling you from my experineces.

as far as cooling, with that size of space you'll probably wanna go with an inline fan. one that will move the required amount of air. it's rated in Cubic Foot per Minute (CFM). to find your cubic feet, multiply l x w x h (i think).


you should be able to figure it out from there.

HPS, yeah, somewhere around there.
