I only wrapped the carbon around mine once and it is working great.

I am asking the same question, anyone know? should i cut a hole in my closet door blowing out or what? any advice would be appreciated as i can no longer have work friends over the house its so stinky goodness.

already working on building my carbon filter... baller thread! thanks

Nice. The guy at the Hydro store recommended a Can 33 Filter with Vortex 6in Inline fan for my 150 sq ft. space.
After looking at this thread, it seems that I can make my own Filter, maybe 1 1/2 feet long for much cheaper, but which fan should I use? Would I be fine with the vortex 4in or should I use the 6in?

Also, how big of a filter should I make and which fan size (or cfm) should I use for a 480 sq ft room? The hydro guy recommened the huge filter, so I suppose I can make one the same size of that?

Both of these rooms are closed off so there is no exhaust, just re circulating air.

There's also some pics a few pages back but the images dont show anymore

Thanks fellas. A lot of good info on here!!

Cheers for the info, im growing on a budget, saw a tutorial recently but this looks alot better constructed and with everyone saying how well it works i'm convinced

Peace

80 cfm is a very small amount of air. At 4" diameter duct, i would doubt it could blow a cigarette off a table, or blow out a match. This may be why you dont notice much happening.

Buddha great advice man great advice and incredibly helpful. I however, modified it just a bit for space and stealth reason.. I took a four inch fan and put it through the side of my stealth cabinet. I took a piece of four inch metal ducting and cut the crimped end off with about 3 inches of the regular pipe still attached to it. I crushed the crimped end around the fan in the hole so its stay and is air tight. On the open I took a rectangle carbon filter I picked up at walmart (I got four of them for 5 bucks) and folded it in half and then taped the shit out it with metal ducting tape because air tight. Now the fan blows down the short duct work and through the carbon filter thats a few inches thick. Again buddah thanks for the help and insipiration
