hey guys I just built one of these wonderful carbon filters and was wondering how many times you wraped the carbon filter around the chicken wire. I only wrapped it around once with some overlap. is this enough? Thanks for your advice! Peace!

well the carbon is what takes the smell out of air. i also use ONA gel its a air neutralizer. the ona gel smells like bounce dryer sheets, so with the filter and a tub of ona your good to grow

I have a grow box that is 5' X 2' X 3.5' I used a bathroom exahust fan and attached one of these home made carbon filters to it. This thing kicks ass. No odor problems at all. I just attached it to the outside of the box. I hear you should probably change the carbon on it every 6 months or so. Hope this helps out.

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

I dont really have an 'exhaust' for my first grow. Just a closet grow, and I keep the door open a lot, though my plants are starting to smell a bit, and they're AK-47s (STRONG smell)... can I make a filter attach it to the front of a small fan and just have that in the closet? Plan the back of the fan towards the plants, so it sucks air through the back, into the filter, and back into the room/closet????

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.

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!! :)

Please help me! I built one from scratch via a guide on planetskunk. But I think that my damn fan is too weak to really make the thing work. I'm still having temp issues and I've got an inline 4" fan that's supposed to push 80CFM. What sort of fan are you running with yours?:cry:

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
