For odor control, I just purchased a carbon air scrubber/fan for exhaust and to circulate air (with passive intake). Carbon Air Filter Scrubber Hydroponic Grow Light Odors - (eBay item 160113833700 end time Nov-30-07 18:02:41 PST) These are the least expensive I've been able to find, the quality seems to be decent, and you could even just let one sit in your room to scrubber that stinky air. :thumbsup:

Haven't received it yet, so can't say for certain.

Good luck with the grow!
