Yes it is distressing. Canadian tire was out of emergency blankets for mylar, and i dont know where to get straight up mylar nor if i can afford it in that form.
I ran into some cash some today im hoping to add two more 6500k CFL's. When i do that i'll see if i can get that Mylar again.

The rubbermaid is quite cool and i had a scheme along those lines. I was going to raise the walls on the cardboard box (advantage to cardboard is i can constantly change it to mount lights), have it lined with mylar and build a cardboard top with the inside covered in mylar.

Odor control might be a problem as i dont think i can keep them in enviroment with air flow controlled strictly by me. Im sure the fan, and a open closet door right next to a open window will help, however im wondering if i can anything that eliminates odors without being a filter. Hell, it doesnt have to be eliminated just minimized. Also considering i'll only have 2-3 plants post sexing the smell shouldnt be TOO bad, no?
