Closet grow odor/exhaust help.

Just got done with my first closet grow. The main thing that I noticed I need to invest in will be some sort of odor control and better ventilation. I have a quart of ONA in the closet but its not quite enough. I am looking for better vintilation also, so I figured I can get both with some help from the readers. So I guess I am asking for ideas with budget in mind. My closet is not very close to a window, but fresh air is not an issue. I dont know where to vent also. Right now I am just letting it vent into my apt atmosphere. I am on the bottom floor so Im concerned with venting into the walls, but thats one of the things that I have thought of doing. Any cheap "scrubber" ideas?

You could always place some ONA inside the ducting of your exhaust and this will also help with the odor.

For a closet with no ventilation what so ever you cut out (plan to replace door if your renting) a 6 x 6 or 6" cirlce at the top of your door so you can expell the vented air that is scrubbed with this https://www.rollitup.org/indoor-growing/7074-easy-build-diy-carbon-filter.html (place ona gel at exiting end of venting/ducting). Make sure the ducting connected at the door is long enough and flexible so you may open/close the door conveniently. Incase your wondering... http://media.photobucket.com/image/inline%20fan%20diagram%20grow%20room/pacman322/VentilationDiagram2.jpg I would place the carbon filter before the light. Why pass uncleaned air over your pricey bulb? Hope this helps and when your done blaze one for Mylar!
