Thank you very much for all the responces and thank you BlazeIdo for finding the link for the fan. I am on a tight budget and was wondering if you had any $100 suggestions that only costs $20 or so lol. I have about $80 more I can put into this grow and that is going towards $40 in lights, and $40 in venting. The Lowryder strain doesn't smell much and now that I think of it, I won't be needing a carbon scrubber since I have my ionizer running, a grow room full of herbs below it, and a can of ozium incase smoking bud stinks up my room.

So how about an exhaust fan that doesn't have to push through a carbon filter? I have about 11.2 cubic feet of growspace and I am trying to change the air every 20 seconds or so, so how about an 60cfm computer fan?
