lol! Home De POT anyone?
Did you get the foily kind or the plain white kind? You can spray-glue mylar camping blankets to styro insulation slabs and actually build totally modular grow huts of them! Connect them with 3" sheetrock screws and check for light leaks, and you're good to go.
Bonus is that you don't need a lot of tools to build this- just a utility knife and if you are feelin' sassy a power drill.
