im currently growin in a 36"H x 27"L x 15"W rubbermaid stealth box. i currently have 3 plants in it now, about 10-12" tall. under 7 cfl's 1600 lumes a bulb. I also have a 250w hps that i would love to use but the temp got way above 135f even with a cooltube setup. so i am currently tryin to find a good cooling method for it for my space.

but back to what YOU were sayin... I think if the 6 in your mentioned dimensions is the height and you have a really good exhaust fan, you should be just fine. as long as your temps dont get above 90f you will be fine.

good luck:thumbsup:
