That is correct. "Mounted" about as high as my light currently is.

so blowing the carbon with the fan removes the smell? :S
i thought you had to draw all the air out of the room and force it through a carbon filter for it to work effectively.

Actually the air in the room is being constantly turned over without outside venting. With the carbon on top of the fan, the air is being drawn through the carbon, not across it. I suggest a better understanding of the concept before you attempt to troll.

Sorry,wasn't in the best of moods the other day. The carbon is directly on top of the fan, and the fan is pointing down, blowing down that is, towards the ground. Since the the carbon is completely covering the grate of the fan, the air is being drawn through the carbon before it gets to the blades and is pushed down and out. Since the air isn't being vented out of the room, it is instead being continuously recirculated in the room, it's simply scrubbing the air of the odor.
Also,it works fairly well. The blue cheese was reasonably strong smelling late into flower and this little setup did the trick in my 8x8 room. Also when the carbon no longer seems to be working, you can throw it all back into a bin and shake it up really good to break it up a bit, creating fresh surface area to give it more life.
Hope this helps.
Cheers

Another option for a very cheap and very effective filter...

Go to Home Depot..
Pick up the cheapest bathroom CFM- 13$
Pick up a 6" or 4" duct T- 4-6$
Get activated Carbon from the nearest pet store- 14$

Put screen on each side of the straight part of the T duct. Turn it so the other side is pointing up. Fill it with carbon, tape it off.
Mount the bathroom cfm on top, let it suck the smell up and blows out through the carbon in the T... all done.

oh, its fine. that gives me a much better understanding thank you :)
i was curious whether it was even possible to recirculate air and scrub it efficiently;
thought maybe vents going outside the house or room were necessary .

haters always want to hate. Problem with humanity is the idiot is aways saying what they "know" while the wise is still deciding if it is correct. I might take this idea and run with it some. Thanks for the good idea. One more idea I would like to throw out there. If you plan on having guests over, invest in an ona block. Before they get there, throw it in. When they leave, take it out and seal it back up. It changes the smell of the room... kinda like a chemically scrubbed smell. Hard to explain but sometimes I swear it was made for cannabis only. I would say instead of just the screen, maybe screen then the padding then the carbon rocks on top of that. Who knows, food for thought. http://www.amazon.com/Cut---Fit-Carbon-Pad-Purifiers/dp/B000U204W2/ref=sr_1_1?ie=UTF8&qid=1394160464&sr=8-1&keywords=active+carbon+filter
With hands together...

You said it swim. Incidentally, it's still keeping my room down on the scent radar. Working ridiculously good on the same bit of carbon I started with.

My take on all of this is that you should just man up and buy a proper carbon filter/ fan setup with an inline ozone gen. This wannabe MacGyver shit that does not really work is getting tiresome. Spend the goddamned money for the products that are designed to do this shit. If not, don't grow until you can. If you are that broke then you need to get your priorities in line before doing something like this.

That was a TOTAL DICK thing to say.

the thing with that box fan setup is that even though it may be working now...it won't for long. Those things aren't tight enough to draw through carbon effectively

so a lot of the air that is getting blown out is actually being sucked in from the front because of the resistance of the carbon on the back.
so you may get some absorption of smell just from ambient air but not much from it being drawn through.

light a cigarette or joint or something and put it around the fan and see where the smoke gets sucked in or not...easy way to test it.

You can make very good homemade carbon filters but not cheaply or easily. for a filter with any size

My wife loves the smell, perhaps spouse exchange during bloom? If you are going to use a masking jell do make sure to include the spouse in the selection of scent. Many people hate "white linen" for example.
