I mean I guess there's levels to stealth, but a 2x2x4 in a storage spot under the stairs as opposed to a 6x6 in a bedroom is stealth to me. ;)

I agree with @Tracker, the 4ft height will hurt you. I grow in a 2x2x4 because it fit well in my stealth location, height is a bitch. Moving locations and upgrading tent size for the next grow. Fuck stealth...LOL
