    I keep an earthworm bin in my grow room. This absorbs odors so well that I don't use an air filter at all. The worms don't smell bad at all. The castings don't smell bad either and I use them to mix with soil. I haven't read all 900+ replies so this may have already been said.

    I bought an Oreck air purifier, the Professional XL model for our living area. I put it in the growroom one day just to see if it would work.

    Its all I use in there now.

    I do put small deodorizers right where the air comes out of the fans on my chambers, since there's still a slight smell. That takes care of it though. It's an absorb and mask system. The big air purifier in the room then does its part too, just in case, and generally keeps the air moving in the room to reduce any condensation or whatever. The carbon pad on the AC was just a "might as well" thing. Anyway, the whole thing seems to be working okay. Smell is the biggest tip-off of a grow and can actually carry quite far outside a building just from natural cracks around windows and stuff.

    Hi all,
    Noob here, not growing but interested in starting to. I've read most of this thread, what I mostly got is Ozone = effective but bad for you and plants; Carbon filter = Good but it cleans the air, doesn't "kill" the smell. Someone(won't quote cause don't know where in the 47 pages is) said that Ozone is not harmful when in water it's even good for plants. Has anyone tried to spray the canopy with ozonated water? it's supposed to kill mould and other bacteria and hopefully help take care of the perfume

    @bartow I'm interested in the earthworm setup, could you explain a bit? :)

    Carbon filters do kill the smell. Just that you may need a lot of it to completely remove all trace of smell. You're probably thinking of a hepa filter. They just remove particles. I also wouldn't suggest spraying water on flowering plants. It would increase humidity too much.

    I am no expert. Back in 2013, I ordered 2000 earthworms from Uncle Jim's Earthworms. I put them in a plastic bin and started giving them vegetable scraps. They double in population every 90 days. There are lots of youtube videos on earthwoms and that is where I learned anything I know. I is not rocket science. My grow room is just a wooden shed with a tiny ac in it, divided into vegetative and flowering. With the worms, the odor is unelectable unless you are a dog.) (I guess a dog could smell it. I don't know how it works but earth worms and castings just absorb odors. If I feed the worm cantaloupe rinds, there is a fruity smell inside but nothing inside. That is about it. Sometimes I have as many as six plants in flowering so there is a lot of odor to kill.

    That's really cool @bartow thanks for the info, I'm curious now if the worms/composting would also help with some CO2 too, I'll have to look it up :)
    @BobCajun Would it be a problem even with good air circulation? Also, isn't the problem of high humidity the increased risk mould, which the O3 in the water would kill? Sorry if that's too stupid of a question.

    One of the things I lack is sophistication. All I do is try things until I find something that works. I don't know anything about CO2. The worm/odor thing happened by accident. I originally put the worms next to the growing because it was a good place to up them. I don't know anything about mold either. I have just been lucky with that.

    For a small grow tent with LED lights, is it best to vent the carbon filter inside the tent or outside the tent?

    Either drive filtered air from the tent, or filter air that you are pulling from the tent.

    This will give the tent a slight negative air pressure. This will help keep the smell
    from escaping into the room the tent it in.

    I'd say the filters are made to be sucked through, not pushed through. So for that I would put the filter right under the tent roof to catch the warm air.
    In some article I've read to look at the tent slightly bowing in s a proof of negative pressure. That's sort of true. But you can have that happen without any air going in and therefore nothing gets vented.

    Thanks,

    I read that you can set up a carbon filter to exhaust filtered air out of the tent, or as a scrubber where you just vent the air through the filter and back into the tent. You can only do the 2nd option if you use LED lights because of heat issues. I was wondering what works better. Also, will a carbon filter work for the stinkiest strains?

    I wouldn't do that with my led lights, for sure. As a matter of fact, I wouldn't do that no matter what. But that's based on my setup and parts.

    This is what I do as well.

    A negative pressure in the tent makes sure that there is no leakage, yes.

    So this is a touch of my diy addressing ventilation and odor my own combination of several things I've seen..... carbon is in the T 20161201_140706.jpg 20161201_131554.jpg 20161201_125857.jpg 20161201_125813.jpg 20161201_122218.jpg 20161128_182626.jpg
    Amount of chemicals used.... 0
    Ventilation project:
    Time spent 30 minutes
    Lowe's $38
    Wal-Mart $10
    Bowls smoked thinking about it . ... :bigjoint:unknown.
    Sitting in the best seat in the house watching TV . ...... priceless
    For everything else there's bong rips....

    To all threads I'm in I will somewhat abandon after this round harvest to go back underground stealth, I'll be watching and pop up from time to time.

    Hey, just to put my two cents into the matter of Ozone. Ozone is widely used in Europe and middle east. I choose to use ozone for my grow because I cannot afford to give out noise of any kind. I also have limited room.

    One thing I came across in almost all the ozone threads here is user error. I understand you guys want to have the "best" of the best. But with ozone, best doesn't mean best as we know it.

    Here is what I mean by that... you have to match your mg/h to what you have. Going over to amazon and just buying an ozone device with 400-600mg-5-10g is a good wait to hurt your plants as well as yourself.

    Always match your purchase to the area you grow. It will be easier to control the effects, to find that "sweet spot" of running ozone and turning it off. If you are in a small ass room with a 10g ozone device, good luck figuring the safe zone without ruining stuff. I saw that a lot. People fail there and blame ozone for their actions. Ozone is unforgiving.

    You don't buy a SUV and try to take corners like its a ferrari.

    You don't buy a rocket launcher and try to shoot at people like its a pistol. You will blow yourself up too.

    Get it?


    Anyway, in near future I will be using ozone on my grow. There is no smell yet. You can check my grow journal if you like.
