Hello all, I cancelled my last order for a grow tent because i found out it was pretty shitty. I was referred to this one. It's really cheap so i'm still iffy about buying it. can anyone tell me if it's worth the buy? http://www.ebay.com/itm/Hydroponic-...nhouse-System-Mylar-36-x-20-x-5-/330836827078 Thank you!
