The Ultimate Odour Control Thread

[Javadog]

I am growing kushes and had to add a second carbon filter.

It just takes it own share of air out of the tent, through the filter
(a "can filter"). This does have the effect of increasing the inflow.
I now have lengths of ducting hanging out of each free port
(three of them). I hang the duct down so to prevent light leaks.

My original filter is a very large DIY model that performed admirably
for two grows, but seems to be losing the OG battle.

I have also noticed that the discoloration of the prefilter that surrounds
that filter body is indicating that there is more air flow on the end of
the filter near where the duct attaches. This makes perfect sense,
as the air will find the shortest path.

I am going to wrap that end of the filter in plastic which will force the
air through the less used end. ...and I will not make four foot long
filters again. :0)

Onward and upward,

JD

I use mountain air carbon filter. Cheap and works great. Zero odour

 

[TokinAllDay]

Could i use a microparticle ac filter. or 2 stacked on the back of a box fan. or am i being stupid thinking it would filter out the smell.

 

[sourpuss]

Invest in a decent carbon filter, inlinr fan, I got both, mountain air, 350 cash cad. Speed control, key for noise,

Lasts over a year. Cheap, pretty light as well for shipping, compwred to competitors. I have a supplier within drivin dist.

NEed to run these as an rxhaust from the room to b most efficient, as opposed to scrubb.

Very excited to try some of these things when the time comes, but I have a newbie question! When does it start to smell? I would assume during the flowering process, but I know that I could be wrong..

Hi all,

You probably have heard oh yeah this is the shit it does wonders and then you are never fully satisfied with it? Guys it's here! No need for ozone generators and expensive ona gel/block that really just blend with the weed smell somewhat weakening it. I went to my local growshop yesterday complaining about smells and the guy starts raving about this new odor neutralizer they have and was tested in a 80 plant room and they said they couldn't smell shit, moreover if it doesnt work the company will take it back. For 90 euros i thought ok fuck it lets give it a go, still wanted to get ona but the guy did not let me take any saying that will be plenty. And by god was he right. Just 30 minu tes after puting that little machine by the air intake it stopped reaking out the carbon filtered exhaust (kush can really stink ). I swear to you guys that the smell of cannabis is gone! It has been replaced by a smooth nivea after shave smell WITH NO cannabis smell behind it whatsoever. I'm officially in shock. Best money i have ever spent on odor relate stuff and I reccomend everyone to get one NOW! The guy at the shop says he's not replacing his carbon filter anymore for his personal smoke grow, just using this.

They even have a small one for the gaff! That has to b e the shit for all those whio are constatly stressing out about the neighbours smelling brunt goodness.

I am growing inside of a 6' tall cabinet. I have two exhaust fans in the top that have a bit more power than my intake fans so that I get a negative suction inside my cabinet. I mounted a Rubbermaid container over the two exhaust holes on top of the cabinet and sealed it up with some silicon. Then I put an activated carbon felt pad over the bottom of the container... Then a hepa filter over the top of each exhaust hole. And then filed the rest of the Rubbermaid container with cheap activated carbon pellets. From there, I cut a hole in the lid that fits over a final hepa filter and then from there it is vented into my attic. See pics below

I just bought a Phresh Filter after using ebay knock offs over the years and It worked 100% better. 10x10 room 400cfm inline with 550cfm filter.

I loved my DIY filter, but have to admit that my Can-Fan is smaller
yet doing a better job.

The cost of the carbon alone will be half the cost you would have paid.

Just a thought.

I got a new type of odor filter that uses a blend of carbons and chemosorptive media. I was looking to do a little write up about it and found this sticky. It's made by greengatorfilters.com and is doing a great job so far with my blueberry skunk,critical kush,deathstar and LSD strains I'm growing.

I got a buddy that wants to make one. What carbon did you buy? And were? thanks

 

[Javadog]

When you go to buy the carbon, you realize where the money goes
when you purchase a pre-built model. It is not cheap.

Do a lot of research for a best price online.

Maybe someone can beat what I found? (I have to believe so ;0)

I bought Acurel Activated Carbon Pellets from amazon, in 3 lb bags for $6.47 each.
This price does not seem available at this time.

Actually this is the best prices, per pound, but the shipping is nuts.
(go to Acurel's site and find a local reseller. That is the best route)

Good luck,

JD

Have you guys seen this? http://www.aliexpress.com/item/Free-Shipping-3G-hr-CE-Approval-Air-Purifier-Smoke-Eliminator-Portable-Ozonator/626517208.html I was servicing a grow and saw this little box in the corner of his work area, turns out it was purifying the whole house air! Seemed to work fine as his house was...well normal. Its a monster grow though. I also have seen these being used more and more http://www.planetnatural.com/product/uvonair-ultraviolet-ozonators/ as room deodorizers. A little pricy for what's there, but maybe for a stealth grow or something? All I know is wherever I go if they are using an ozonator they are not fighting smell. JAS

Ive go two o zone generators they work great.Just wipe the bulbs and fans down from time to time and no one would ever know you have a grow around.I was using some ONA too.i like the stuff but if you get it around your plants YOU WILL KILL THE SMELL RIGHT ON THE PLANT WITH IT.

 

[AlBundy]

I once read a post on a different forum where his grow was near a floor drain so he obtained a small blower unit and ducted it straight down the floor drain into the sanitary sewer. Untraceable to say the least.

 

[Javadog]

Hmmmm...I believe that they typical "trap" system might make
this problematic in many installations.

Not a plumber though....

[ilikecheetoes]

ozone machines give me a headache and they smell funny. They arent all that healthy for you. The real ones are banned in california (not that that means shit, treehugging shitbags) You can only get thee little car sized ones that dont work anyway.
They can damage electronic equipment as well. I think they eat at the wiring but that could be hearsay and conjecture.
But they do kill some smell Ill give them that.

And the venting into the sewage would only work in some ratass third world country.
He in the first world we put in U traps to keep the smell of human fecal matter from permeating the house. Rwanda maybe not so much...

 

[jela10]

Here's the way to use ozone...buy a "Big Blue" and put it inline with your exhaust....I got the 4"x20" model but have never installed it as I fixed my original problem (perforated vent line)...I did use it to disinfect the tent after a white-fly infestation. Just hooked up a 4" duct booster to it it and set it in there for an hour. Smelled like a lightening storm in the tent for days but there was never a bug again. I heard these things are used by car dealers to rid the cigarette smoke damage from upholstery. The Big Blue is powerful and when placed in the exhaust line will never hamper the grow environment. Just watch where the exhaust it vented to, as that area is gonna smell "different" to someone suspicious. It should dissipate faster as a gas than typical air loaded with turpenes.

I just found this thread after posting my simple, cheap, and fast to construct carbon filter idea. It would only work for small grows. I used it in a veg room that was getting very stinky. It works well though some may take issue with the use of cardboard. 3 items to construct, under $20.
