Well, to start with you have two systems; The circulating system, which is the fan that blows around in your closet and the Intake/exhaust system.

Take a look at this cab I built and you can get a good of how a intake/exhaust system should work.

For the poly stuff, Check in a hydro store or google "panda poly plastic" to find it online.
