How To - Carbon Filter

[12345-54321]

Heres my 2 cents.

I've made 2 scrubbers in the last few months. one 4" & one 6" using depot line fans. I used simple fencing wire (rabbit wire) along with some weed blocker material (used in landscaping, they sell large & small amounts) for the screen sections. For the inner cap, just duct tape it over, and the outer cap use a .89c 8"-10" flower pot base. Then the cost is really just the fan and the charcoal.

Whether you are pulling the stinky air through the scrubber and then out or pushing it through and then out, the result is the same, clean stink free air. Think about it, the stinky air has to pass into the fan ducts' airflow one way or the other....

A little side note is that the carbon for a larger unit will run about $40-50 depending on the store. You'll need roughly 10 pounds for the larger unit. (4-5 28oz bottles-Petco, $9.99)

Hey, great how-to post here,

I'm planning on making one of these in a little bit but I have a few questions.

Where the hell can I get the activated carbon?

and

Would a carbon filter be any use for growing in a walk-in closet?
Would I just put the carbon filter in front of my fan?

Cheers!

wow i still dont understand

could anyone put up some pics of the fan the carbon filter and their grow room connected. that would be great :rastasmoke:

edit: nvm i looked a little closer. :stoned: too much

[thecreator]

Kitty litter hmm I like that idea not suspicious at all.

[smokedoja]

iono if its just cause im stoned or what, but the end without a endcap the 6-4" reducer part, how do you keep the carbon from spilling out into your ducting and how do you seal the inner screen in the reducer so that you get the most suction through the carbon....?if you could post a pick looking down the reducer that would clear this up for me...thx man


edit, ok looking more closly i can see how you made the seal, but the reducers i get at the depot dont have a lip on the inside were i would clamp the 4" sreen to, do you put in a 4" collar into the reducer to get this lip?

I was wondering this also. I made this so long ago that I forgot. It looks like I put the lip in there because there is tape all around it. I would assume yes i put a lip in the reducer

OK, I just got all the supplies from Home Depot and im having the same problem as mellogold, the reducer i have doesnt have the lip/collar on the inside... could you tell me what to buy and how to put it on? is it taped or what? it looks like the end of some non-flexible duct....

Hi everyone,

My first grow is rapidly approaching and I wanted to run my idea by a few of you more-experienced types before I go ahead and ruin it.

I'm very limited on height, so I was thinking of making a shorter filter, but with a larger diameter. I would probably have two fans blowing into it, but I'm not exactly sure yet. To fasten it to my box, I was thinking about just getting....you know, those u-shaped things with the pointy ends. The last thing I was thinking about was using some of these instead of pantyhose. (I have a bunch lying around.) Do you think they'll be breathable enough? I can't say I've ever tried to move air through pantyhose, so I really don't have anything to compare it to.

Oh, and while I'm thinking about it, I've looked at some fans and some say on the package the amount of decibels they put out. Some do seem a bit loud, but I was wondering, how much does being inside a wooden box lower the noise level?

Thanks

dude that is kick ass so far looks as good as store baught and sounds like it works good . thank god for making people like you i thaught i could come up with some home made stuff but that is just bad ass good lick and peace out..

[CheeseOnToast]

you'd be much better off replacing the carbon with silica gel, or maybe mixing the two. Its hard to get hold of through.

[mushaboom]

can anyone further explain how to put a lip inside to seal the thing? i dont understand what you mean by duct tape it over
thanks
