serious odor control?

[Cosmic Surfer]

being that I do not know where to put this, security/legal issues seemed as good a place as any. I heard proud breeders boasting their stuff is so potent and smelly that even double, or even triple chaarcoal filters were ineffective, if that makes any more sense to you than it does me. med man maybe? if this is really so and you are not a registered med grower, how do you mask the smell there has to be a way!

I like a combo of Canfilters and hepa. Peace GS

... and if you want a robust overkill system you can really trust, you can always use Ozone in a lung room downstream of your Carbon filters. Powered via a computer UPS like a "redundant" engineering system you are also going to be smell free even during power cuts or when your filter decides to give up filtering.

2 carbon filters with 1 fan between them. You choose the size. Runs 24/7 in your room. Of course, this is in addition to the standard odor control methods and not meant to supplant them.

I got this idea from another member. Works well for me.

Have a nice day. bg

carbon ,ozone and ona.

Can-75 in my room, drawn out through 6" hard duct to a plenum box that holds a Can-100, with a 8" Vortex 747 CFM fan pulling through both filters. 8" flex duct up to the cold air return on my furnace. Furnace fan set to run constantly.
In a med state, but my neighbor 150' away is a narc, with a dog. He walks the damn thing past my house all the time. I just wave.
House full of teenagers for a birthday party, not a worry.
Have grown Nirvana Aurora Indica under 2400w this way. That is a brutally stinky strain, and still no smell.
Take a look at the WC pressure charts on Can Filters website. You can fairly accurately calculate your flow/fan combo that way.
Overdrawing, or even approaching the max CFM rating of a filter is asking for trouble down the road, if ultimate stealth is the goal.
ONA is awesome stuff. I thought it was snake-oil, until I got a quart from a buddy. Never bad to have in your reserve arsenal.
UPS for a PC won't run a fan very long, but a cheap inverter from Walmart will, or a deep cycle battery MacGyver'd to a UPS (Replacing the alarm battery they come with)
I use the deep cycle and inverter, but I have to be here to make the swap. Fast!
I like ChaosCatalunya's idea of the UPS, as it would kick in automatically in the event of a power failure. I'd just look in to upgrading the battery.
Best o' luck!

30 ounce jar of ONA Fresh Linen Gel kicks some serious ass. It doesn't just mask the stink with a scent, it literally eats it and neutralizes it.

You might need more than 1 if your grow-space is large.

The stuff is expensive but it quickly kills the smell of pot (living & smoked), tobacco smoke, stinky cheese, sour milk, bacon smells, cat shit, spouse shit, you name it.

The trick with making the gel last a long time is to periodically fill it up half way with tap water, put the lid on, give it a good shake, and Bob's your uncle! It keeps on keeping on.

I live in a high density urban area and have a small grow setup in my spare bedroom utilizing about 1000w in lights total. I literally live in a highrise condo. I use twice the recommended size charcoal filter(I use a 24" phresh filter pulled by a 452 cfm fan) scrubbing the room in intervals that equals 18 hours a day, and a Ono automated mister that spritzs Ono every 30 minutes into my grow area. Sometimes a little smell creeps out, mainly when I have just trimmed some fresh flowers. I will add more filtering capability,or go to filtering 24/7 and add more odor absorbing power if it ever becomes unmanageable. We have several tenents in the building that are pretty open about their cannabis usage and often blow up the common area in cannabis smoke smells. So I try to look the part of nerdy guy and if any smell causes suspicion to any grow rippers, they will be looking at my brazen neighbors,not me.

There should be no smells if your using a decent carbon filter and that and your ducting is fitted correctly meaning you have positive pressure no matter how smelly the strain is ,its just more bullshit from breeders trying to sell more seeds ,take anything breeders say with a bucket of salt

 

[trem0lo]

A proper carbon setup should filter 100% of the smell, no matter what strain.

Doubling up on carbon filters is certainly a viable option, as is ona gel.

Don't forget to replace them more often than needed. I find they filter better with fresh carbon, especially in the final weeks of flowering where smell gets ridiculous. At that time, I replace my small filter's carbon weekly as sometimes you can detect a faint "eau de cannabis" if you stick your nose to the exhaust. After I replace, zero smell.

My little DIY can filter uses 8x16 mesh carbon. Any bigger and I have to turn down CFM. Any smaller and I lose airflow, raising temps slightly, but it filters better. Some companies use large carbon pellets, which I'm personally wary about but probably work fine with proper bed depth. You really have to experiment, and if you're getting smell, adjust.

cc, sounds great but you lost me from the point where you mentioned lung room? Could you elaborate in a simple way and/or provide links? sounds great though!

Lots of diverse answers, I guess there is not just one solution but many. Now to figure out what would work best for me. thanks everybody!

 

[wantaknow]

its a space where you would dump the filtered air ,and have a ozone generator in that space so the scrubbed air would have time to dwell there and let the ozone attach to it

 

[Tongue of Truth]

High quality filter, with a fan capable of properly providing enough flow. (been using Phresh ever since my locals got it) and a Bucket o' Ona. You'll be golden. Proper ducting fitting is key as others said. We had at one time 30 hydrofarms in a 2b2bt townhouse, in a non med friendly state, and LIVED NEXT DOOR to a boy in blue. ( We hadnt known for quite sometime, no car/uniform was ever seen til one day...). my chime. be well. ToT.

Hi CS, sorry... O3 needs a space to mix and zap [oxidise for the technically minded] smells.. You can get inline duct O3 machines, iirc more on the large commercial side, there is a problem whereby O3 generates acid that inconveniently eats stuff in ducts, a "lung room" is just a room or space where the Ozone has a chance to mix with the air thoroughly before leaving the building.

Carbon filters are great, but, most people tent to notice they are dying when the place starts to smell, and what happens in a power cut ? That is why a secondary system [redundant] with a UPS could just save your ass.
