just wanted to share what i found. its a breathable fabric closet for clothes. i was thinking if you lined the inside with mylar or that white film, it would be easy to cut out holes for intake and exhuast, it should be able to support lights and scrubbers, when lined it should be lightproof, and comes with a zipper.....they have single wide($20) and doublewide($40)....check it out!!!
