Hey I had the same problem setting up my closet grow. I ended up getting a pretty sweet grow tent from homebox.com. It's light proof and has some sort of white reflective material on the inside (mylar? I'm not sure), as well as intake and exhaust ports to set up a ventilation system. The XS version fits in my closet perfectly and is just big enough for my 2 personal use plants. It's $100 but the best money I've spent on my grow so far! Hope this helps
