NatrlHgh just run to any home improvement warehouse and grab some 2x2s and a few 2x4s and make a wood frame that suits your space reqirements.. using some duct tape and/or alum. tape and a staple gun just wrap the frame in black/white panda plastic. make sure the plastic is good and secured. then go buy a tarp zipper. easy as cake to instal. then just cut another piece of polly platic to place over zipper taped on one side and buy some velcro to secure the other side( so no light leaks through the zipper) then just add lights, fans, etc and your off.. a 5x10 diy costs an 1/8 what those snazzy ones costs and if you upgrade it won't cost an arm and a leg for more plastic and a couple of pieces boards..plus its eaasier to customize to your specifications:) hope this helps ~Bhanghead
