My grow cabinet was built into the garage, and obviously I had some issues with smell on my last grow. I started off with a simple solution of putting cat litter in a tray and keeping it moist with pine-sol. It did its job but made for too much attention to keep the smell fresh.

While I was shopping a month or so ago, I stumbled across these Air Wick Automatic Spay Cans. Since installing, the whole garage has not had one single scent of my plants. They're relatively inexpensive, and seem to be working very well at this point.

Thanks for the replys guys they helped especally the muffin fan in the bucket idea. again thanks
