Hey hey everybody
I started this thread because, well, I'm having one hell of a time controling the smell from my PC case grow.

I've tried all manners of DIY carbon filters except for Red's deisgn (because it would look really out of place next to a PC case and kill the stealth factor) and no matter what I do it seems like I can't get the smell under control.

So far the best option I've found was to use True Air replacement carbon filter pads and sandwich them up against my 50 and 80 cfm PC fans along with some dryer sheets. I also have an ONA block sitting ontop of the computer cases.
Before that I tried refillable bags of activated carbon from the pet stores and bulk carbon in all sorts of home made carbon filter designs. But even with a heavy load of carbon and ONA blocks my computer room still reeks like the chronic every time me or my fiance walks in there. Just for reference I'm growing Sensi Seeds's Northern Lights, Sensi Seeds's Skunk #1, Serious Seeds's Bubblegum, and DJ Short's True Blueberry. It seems like the Skunk #1 and the True Blueberry are the main offenders odor wise.

Basicly I'm growing with two PC cases setup underneath my desk so any design has to be pretty low key and not look too out of place on a computer. Thus the reason I couldn't really use Red's carbon filter design.
The can style carbon filter's are just too damn big for my setup and I reaaaally don't want to use Ozone due to the extremely small room the cases are in. Using Ozone in such a small place where my fiance and I sit and work all the time seems like just a huge health hazard to me. Plus my fiance says "No ozone, no way, no how. Do it without ozone or ditch the grow."

So after trying lots of activated carbon doubled up with dryer sheets and ONA blocks with no success in controling the odor, the only thing left I can think of would be using some negative ion generators in the room as well.

Does anyone have any recommendation for a good ionizer that would help kill the ganja smell for my micro grow? Or any other suggestions (other than Ozone) that might help a brother out here?

There was a thread on OG years ago (I think it was OG) where someone had made one that was built around the fan. Basically a square around one side of the fan. A lot of people tried it and everyone said it worked good. I never got a chance to try it. If you did that you could put the box part inside the case so nothing abnormal would be sticking out the back.

I plan on doing what you tried (the bag) even though it didn't work for you, it's the only practical thing I can do so I will try to make it work. If I can keep the case sealed and have enough air exchange I'm sure it will work.

could all ways try a low odor strain my ak47 x bubbleberry has very little odor i am running with no odor controll at all... i did a bag seed grow last year and the stuff smelled up the hole house i could even smell it out side the house as well on day i will make a scrubber so i can grow some stinky weed lol

it might be a bit dodgy, but i reckon if you only have a couple of small plants you could get away with just permenantly venting to outdoors. as long as the air always moving i dont think the stench would build up enough to become noticable.

Hello Mr. Micro
I always read your posts on odor control, and you always came up with same new cool ideas for your PC grow. But I guess when you have a really smelly plant it doesn't matter how much you try, it'll always have the lovely ganja smell hehehe
But I found something else for you to try, I haven't tried myself yet, so I don't know if works as they say. Well it doesn't hurt to try and it is very inexpensive.
Basically what this guy did was geting one of those small waterfalls for the living room Like This , and instead of filling it up with plain water he used a mix of water and pinesol(the cleaning product). He claims that outside his growroom it smells like lavander!!! The good thing about this odor control is that it is very stealthy hehehe.
I don't know if your fiance will like this, but I think she will like the pinesol smell better. Everytime I bring the idea of a grow to my wife she ask: "Is the entire house going to smell like pot?" So I think a pinesol smell instead she wouldn't mind.
Let me know what you think of this idea, and if you try it tell me how it worked out!

was just going to suggest the pinesol thing but i saw you already explaned it there pothead. im thinking baout trying it but i think it will just make my house reek unpleasently of pinetrees...

The trick to making a good air filter is to have lot's of surface area with a thin layer of carbon.

That design where the guy takes a computer fan and makes a rectangular box out of cardboard and packs it full of carbon doesn't work because the fan is fully blocked.

I would get another computer case and build a large area filter inside of it. You could mount it side by side with the grow box and cut holes in both to direct the flow from the grow box to the filter.

My computer fan driven filter produces 10-15 CFM flow with 1 sqft of fiter with 1/2 - 1" of carbon.

Hey thanks for all the suggestions guys!

With the carbon filter/dryer sheet combo I got the smell down to about half what it was before, but like I said it's still pretty funky in here.

Venting outside isn't really an option because, well, I live in an apartment building and the nearest window is on the other side of the apartment while my PC case grow boxes are underneath my desk. Maybe next time around I'll go for some more low odor strains, but since this was the first time I have grown in about 5 years or so I really wanted to try some classic strains that I used to get from the locals way back when. Blueberry used to be my favorite smoke with Northern Lights a close second, but Skunk #1 and Bubblegum are gonna be new to me.

But anyway, I sat down and did a whole lot of reading last night (about 4 or 5 hours worth) on negative ion generators and ozone generators. After absorbing everything I had learned, talking with my better half about it, and looking at hundreds of varieties of ion/ozone generators I finally decided to order one of these nifty lookin little things...

They seem to have a very large negative ion output while still maintaining an extremely safe level of ozone bi-product. I plan on putting it right behind the PC cases's exhaust so that any air coming out of the case will pass through a area saturated with negative ions and ozone.

The PC cases are at 90* angle from each other (one to the right of my chair, and one infront of my feet in the back of the desk) and they both exhaust into the same corner. So by placing this little thing in the corner I'm pretty sure it will be able to handle whatever the carbon filters can't.

Anyway, thanks again for the suggestions guys (and gals)! I'll be sure to let you know how the little ionizer/ozone generator works out when it arrives.


Edit: Darn good suggestion Red! I'm gonna have to think about that one for a while!

I was just about to suggest adding another computer case with a carbon filter inside and just have a good fan filtering all the air in the room through there and then I saw red-green beat me to it.

so yeah that's what I would do - just have a full size can filter in it's own computer case with a few fans moving air through it - if you have enough fan to cycle all the air in the room through fairly often or so you will not have an odor issue.

I use a pro carbon filter and I have no smell even with some funky skunky strains - since the intake and exhaust of the cab are in the same room I am basically just recycling the air through the cab and the filter and back around again.

I saw take Red Greenery's advice. He's a micro master. I would bet he could help you come up with something to make a carbon filter inside of another PC case. He's got an elite setup. A good carbon filter will prevent the need of anything else. I grow in a micro cab myself and my carbon filter prevents all smell completely. I think the ozone deal is a waste of money, but that's just my $.02 cents.
