Would this work?

Hey guys I have 2 4-week old plants of unknown sex now on a 12/12 cycle. I have them in a room with cinder block walls and have no way to vent them when they start to stink which seems to be beginning now. I also dont even have the money for a ventilation system if I could install one. The humidity stays between 50-60% and the temp around 70-80F. I have a fan circulating whatever air is in the room but all it is going to do is push the permeated air out into a space I can't have stinking. I have an old box fan maybe 20". would it be possible to secure strips of carbon filters over one end of the fan and just have it recirculating the stinky air constantly, also maybe reducing the heat or humidity? Here's some pics of what's going on and what I'm considering doing only if it might work and be worth whatever the cost of some carbon filters.

With only a couple of plants I don't think you'll have to worry about the odor. You can always get those odor absorbers that come in like a plastic jar.. I have heard they work pretty well.

Don't let paranoia get the best of you lol

have a look in that link,there's lots of ways to build your own fan.

thanks for the replies that ona gel sounds pretty legit to me. I think thats what i will probably go with anyone know a site to get the best deal on it?

ya that's what i was talking about lol.. I know one of my local hardware stores sells it for like 10 bucks each

yea its not really too big of a problem yet its just starting to smell a little bit. I dont know of anywhere around me that sells the ONA brand though, would something like this work?
