How do you make an effective cheap homemade scrubber?

I would like to keep the prices low. I'd like to know the best fan for the buck. Could you all post some pictures of your carbon scrubber systems along with directions if you have the time to explain in addition to their effectiveness. How well do they work. Where can I get all of the supplies locally? No hydro store is near me. I need something quite, relatively cheap (under $100) and VERY effective. Let's see those pics! I know you all have got 'em!! : )

Ponics.

Wow, seriously now guys. I posted this hours ago expecting a reponse when I got back. I would just like a conglomeration of photos and explanations. I want to see the systems people are "currently" using. Thanks again.

There are many different scrubbers to DIY, this one was scaled down to fit my cramped needs....






this is the smallest it can be made (for now at least haha), but have had em large enough for up to 2k

They work great, and have the option to change the activated carbon easily. Cost was around 80 bucks, the larger ones cost the same......maybe 10 bucks extra. Parts from your local hardware store and pet store. Currently it is sucking the air in, but can be used to blow out of also.

Heres one I made. I used wood, hardware cloth, netting from clothworld, carbon, ducting stuff, and some screen material, but probably didn't need the screen tho.

niiiiiiiiice ill make one very very similar to yours man... trully cool

Nice cough cough eer! One question. Is that sealed on the bottom? This is more what I am looking for. The compactness is nice. I would Like to see some more design ideas. What is a cheap online source for good fans? Keep 'em coming guys!

Ponics.

anybody got a copy of that really popular one from OG? I believe it was by someone named SunIsShining... it was similar to cough cough's but i think maybe a little bit easier and cheaper to make, he used a metal duct cap at one end to shape the hardware cloth and I think a duct reducer at the other end...

Here's the FAQ on SIS's carbon filter.Sorry I don't have the pics but it is really simple just pay attention when reading.



All the materials were just under $50, here's the rundown:
Hardware cloth ~ $6 (the steel, not the plastic. in the fencing section)
6" & 8" duct caps ~ $4 (one each)
6" duct collar ~ $2
6" x 8" duct reducer ~ $3
Hose clamps ~ $6 (two 6" clamps and four 4" clamps)
Three 28oz jars of Activated Carbon ~ $20 (from the petstore)
Small package of Poly-fill ~ $1.50 (from wal-mart)
Two packages(or two-pair) Extra Queen size black panty hose ~ $2

Round that all up to $45




Ok. First to build the "core", get the hardware cloth out and wrap it around the 6" cap (for sizing, I suppose you could measure instead), and snip. Leave a few inches to overlap to strengthen the seem.
Be sure to snip so as to not leave a row of points, that will undoubtedly poke the shit out of you, not to mention it'll rip the panty hose.
Once the HC is snipped and wrapped around the cap, use a 6" hose clamp to clamp it down. Do the exact same thing on the other end but using the 6" collar - put the crimped end of the collar inside the core, leaving the tabbed end outward.
Cut the legs off a pair of panty hose and stretch each one over the capped ind of the core, stretching them and covering the entire core with two layers.

So that's the core, it's finished. Oh yeah, I added a 3rd hose clamp in the middle of the core for additonal structural integrity, though it's not necessary.

Next, take the collar-end of the core and set it into the 6" x 8" reducer as shown. Flip it over and tape the collar to the inside of the reducer. I used aluminum tape, but a good quality duct tape should do just as well. Fill in the space between the collar and the core with Poly-fill (batting or anyting of that noture will work just as well).
Once you have that done, it's time to fix the HC to the 8" reducer. Place the 8" cap in the opposite end of the HC for spacing and structure.
Form the HC around the reducer, just as it was done with the 6", and clamp it down using two 4" hose clamp together-running into each other. I couldn't find 8" hose clamps, so I put two 4" together.

Now take the panty-part of the hose, the waste band and whatnot, and stretch it over the outside of the HC. Repeat with the other pair, so you have two layers.

Now for the exciting part, fill it in with the carbon You may need to hold the core at first to keep the spacing even. This will give you a continuous 1" layer of carbon. Perfect.

Leave an inch or two of space and fill in with the Poly-fill.
*Not* At first I built it using the full 24" of the HC, after filling it in with carbon, I was left with about 6" not filled, so I snipped the HC rolls to a couple inches above the carbon line.

Now replace the 8" end-cap, clamp it down, and you're done
To refill, simply loosen the clamp on the 8" end cap, remove the cap, dump the carbon, re-fill, replace cap.


In my bloom room, I'm running a Hurrican 6" 307 cfm in-line. I have it T'd, one line pulling from the sealed, air-cooled hood (which pulls non-stinky air from outside the room through it), and the other line running to the filter. So the filter is actually "underpowered", but that's fine as it allows for slower, more even flow of the stinky air over the carbon. The open design of this filter creates minimal air-flow restriction.

This guy works like a champ, the stinky-ass air that was being blown into the backyard no longer smells at all.

awesome, thanks, Jnugg
If anyone else is building or already has built one based on this design and can take/have pix of the process, that would be a big help too for all of us who have yet to create such a masterful work.

Tokin your current mood says you are dead. WTF?! You ok? I agree...pics would be a BIG plus. How well does it work? Thanks for the good write up.

Ponics.

HAHA I was messin around, seein what all the moods look like and i got distracted talkin to my cousin. I'm fine man
from what I read about it (which was alot, it was a thread with page numbers in the double-digits back on OG) it works great

Yeah that faq had to be one of the most popular faqs around.... Perfect design just like the pro one's you pay 300 + for...
I just got myself and xtra-sun 400 and a 300cfm vortec. Gonna build myself a filter and i'll see if I can remember to take pics... Maybe fill in the blanks for the faq entry..

yea, my design was based on that faq..the bottom is not sealed I just used aquarium filter fluff.

I'd seal up the bottom of that filter unless it's sitting on the floor... Piece of plywood will do.
The air will pass right through like an open tube and not even touch the carbon.... :wink:

Just build a box if you have the room

will the odor leak out of a rooms closed windows? or be worse than a house that smells like weed all day anyway? (from being smoked). if growing in an open closet in a closed room in a house that can smeel like weed?

my idea for small spaces...

my idea for small spaces...

, In my lil stealth box , still being built , I'm going to use activated carbon water filters . I need 4 sq inches of exhaust , since I have a 80 cfm fan that feeds threw 4". Bought 4 1" filters 8- 3/4" elbows , they will fit snug in each end and pipe out ... done $20 Bigger room bigger filters and PVC .. I just went more then 4" for a nice free flow of air ... still to be tested , but sound concept ... I think

cough_cough_eer has the best one ive seen up to date, i like it better than sunishshining's...very cool
