The Ultimate Odour Control Thread

Lacking any feedback, I went ahead and bought a 5,000^3 UV ozone generator and am going to bombard my plants with ozone around the clock. This will be part of a three-pronged approach using Mountain Air carbon filter, ONA time-mist dispenser, and ozone generator. If all that doesn't eliminate the odor issue, I will find another hobby.
Too much O3 in the tent will damage plants (you will get a bunch of small brown spots if I remember correctly). If you dont want shit to smell I HIGHLY recommend one of theses: http://www.blueairproducts.com/ I have one on outgoing vent line, (I run 2000 watts medical grow) with only ONE light (out of 3) turned on, I can literally dump the exhaust into my basement (I have plumbed outside vent, but discovered this by accident when a hose disconnected and it actually smelled less since I have a dry booth there) and not smell anything (well very faint o3 smell). I actually run this way in the winter to save on heating bills. If the power goes out in my house and I dont hook up anything to a generator, in one hour my entire house (4800sqft) smells like snoop dogg came over for a pot smoking contest so its doing a serious amount of work. I also have a carbon prefilter, which worked "ok" but the added ozone made zero smell. I've had ppl painting the outside of my house a foot or 2 from the vent and nobody can tell. Ozone is amazing when used correctly(need a decently long run of duct to insure adequate contact time).

I have activated charcoal in my ac's intake, then ducted back into the flower room
works good for smell but I use it mostly to control temps

the pics are without the intake box, which has the charcoal in it with a duct back into the flowing room
there is always enough ductape :D

I grew some Jock Horror in my closet, and tapped into a drain vent pipe and blew the air out the roof, BIG mistake! My neighbors thought I was raising a herd of skunks in here! I'm trying some Blue Mystic because the seed bank claims they have a neutral smell while growing. I'm curious as to the potency of a strain that doesn't stink. In past experience, the more the smell, the better the buzz. I hope this strain proves that theory wrong. I'm attaching some pics of good ole stinky Jock Horror, ahh the memories... Me and my wife both stayed mellow for several months from 2 plants!

I'm thinking about investing in an activated charcoal filter for my closet grow area, that is if the strain I'm trying now doesn't live up to its promises, to be potent and not smell while growing.

Growing Blue Mystic auto flower, I've got a 400watt MH and a 400watt HPS. With a regular flowering plant, I knew what to do, MH during veg, 24hours/day, then during flower stage, HPS 12/12 on/off. Duh.
But what about auto flower, I've heard 18/6 is best, but should I use both MH and HPS? Or is 800watts for 4 plants in a closet too much?

sorry i dont have time to read all the 73 pages just read first one
but did anyone mention any air purificator?
id love to use one as it would not be complicated if it works well to finish my grow, if its bad then id have no choice to turn into ona gel
will use DIY carbon filters on next grows

ty for answering

I'm like you, I don't want to read the whole thing, what is the DIY way to make an air filter? I'm going to need one, really bad here shortly, right now my ladies are in veg stage, and not stinking, but when they start turning, I'll have to have one. Last round made the place smell like a massacre of skunks that was obvious to anyone even driving by!

My apologies if this has been talked about, I did search.

I have a 54inx36inx84in flowering tent. Originally I was going to do a 6in Vortex, carbon filter, duct silencer then insulated ducting out to the attic.
Now shopping I see a 6 in vortex S line quiet motor with a carbon filter that is %50 cheaper.
The s-line is 347 cfm and standard vortex is 449 cfm. Based of internet theory one can do Required Fan size (CFM) = (Volume of Active Growing Space) x 1.33. Redneck mathsays about 140. From what I gather this may be a option without needing the duct silencer. Space is tight.

Thanks for the info thedude27. I believe the plant damage you are describing is caused by nitric acid which is only an issue with the CD type ozone generator. Anyways, I had to put off using the ozone generator until just a few days ago. I am using the unit next to an unsealed closet and there is no way to vent the ozone anywhere. The unit kills the odor but it is overkill and I am trying to dial in a lower output by using a timer. At the moment I am using a 15 minute minimum timer and it smells like 15 minutes may be too long for an "ON" cycle. Looks like am going to have to switch to a 1 minute minimum digital timer.

If anybody has experience with dialing in the "ON" time of a 5000^3' ozonator for areas less than the output specs, I'd be glad to learn of your findings.

Hello guys I have a question! I was looking at cheap carbon filters online and stumbled across Rhino Pro Filters, I noticed they don't come with those pre-filters, is it necessary to get them with Rhino Pro Filters?? I don't mind buying it, just wanna know if it's a must, thank you happy growing everyone :)

The pre filter is the same stuff they use in reverse cycle air conditioner filters. I can't see it causing problems not having it on there unless you have a dusty environment or the carbon is not properly contained in the filter.
The main thing is the activated carbon, that's what takes the stank out.

Hi.. first-time grower. I have a 4x2x5 grow tent I am setting up in a closet in my basement. I have a carbon filter and am looking into ducting the output. I would REALLY rather not have to install a duct vent on the exterior of the house, and the room outside the closet is quite large. My question is, assuming I am using the correct fan/filter combination, will there be any smell if I duct the output into the larger room?

Thanks!

I use my closet, about the same size as you described, I just got a carbon filter and fan, and I don't use any duct at all on it. I kill 2 birds with 1 stone with it, and have it blowing on my plants. I keep the doors closed, but it is by no means sealed, and the filter controls all of the smell so far. When my girls first started to flower, they started to stink up the house, but since I put the filter in there, it's pretty much gone, 95% anyway. I do suggest getting a big filter. I get 95% control out of a 4" X 12" with a 250CFM fan, so I bet if I'd gotten a bigger one it would control it completely. Good luck and happy growing!

I use a 12" fan on a 12" x 39" phat filter to scrub room air mostly for when venting stops during lights out. When lights are on I pull air thru the hoods thru blower thru uvonair cd-1200 thru about 15' of 12" duct and out thru wall vent.

Sorry for the delay on the greengator filter write up but I've had some health and personal issues that I've been dealing with. I've been using the filter for going on 6 months now and am very happy with its performance and have virtually no odor coming from my grow area. I have 5 plants in flower most of the time in seperate tents and cabinets and have seperate ventalation on each of them exhausting into a large room. I've got the greengator filter set up on one end of the room and send the exhaust through a duct to the other end of the room so my air moves from one end to the other in a loop. It's doing a great job and I only have a slight odor when in the room and can't smell anything outside of the room. I really like the design features like the magnetic collar with a built in seal where you attach your duct work,easy to change outer pre filter,built in eyelets for hanging and the ability to connect more than one filter together. I plan on using only greengator filters from now on. Took a few pics to show the different components.

Captain Morgan, sorry to hear you haven't been feeling good hope everything works out. Great to hear the filter is working out for you! Check out our blog, were starting to get some great reviews. http://greengatorfilters.com/blog/
