In post #3 you asked if you could use the plastic to section off your grow space. I'm assuming you ment from the rest of the closet since you said the back area was going to be your grow. Yes, you can do that. In that plastic, cut out in take holes in the bottom, go to walmarts or where ever & get a sm round fan, cut hole to fit in the top of plastic & mount the fan blowing outwards. On the back side of the fan, place your charcoal pad. If it gets too stinky & this pad doesn't handle the problem, get a fan forced charcoal air cleaner with ion/ozone emitters. They come in various sizes & prices. You can get charcoal pads at petsupply places for fish tanks. If too sm. Sew some together to met your size needs. Once you get this all together, just leave closet door open untill you need to hide it. If you build up too much heat, get another sm fan & aim it at the lights. I would burn scented candles in the room the closets in. I like the smokers candles from cig/tobacco stores. They're designed to cover strong odors. ~~~ PEACE! ~~~
