Hey TrickDaddy: I hear ozone generators are the thing for you. There is an article in the Best of High Times 2006 issue called the Perilous smell of success. Maybe you can read it online.

If someone is home alot, maybe you could spray air with Ozium. It is an aerosol product usually found in the auto section. It really masks smells. That is the only other CHEAP solution I can think of. Hope it helps. I use it to get smoke smells out of car etc. I like it.

Be careful of the cold winter breezes in that window!
