I'm gonna make this blatant.
O3 might work for a "pc grow" but will not work for a couple decent size girls or more.
IF you are in an area where you
must keep it "stealth" then o3 is not the choice your lookin for.
Yes o3 is a miracle odor eliminator , but its just not feasible in a grow area where odors can and will get strong. It
can be done , but no regular "gardner" is gonna put this system together and get it to work without way too much time and space, frustrations ect..
Putting o3 into your vent is a 100% waste of time an money if your always circulating the air like most do.
I personally built a system with 1000 mg/hour of o3 and used a 400 cu/f dump room to clean the dirty air an then sent it out the roof. it did not work at all, so we put the outake on a timer to let the dirty air sit with the o3 for a longer period of time an that caused back pressure in the stink room forcing the dirty air right where i didnt want it....... SO we sealed both the dump room an the stink room (which is only 500 cu/f ) to airtight status. and still by the time the o3 cleaned the air , the stink room was not getting enough circulation , causing heat build ups, low co2 levels and just plain bullshit.
i am the cheapest fucker on this site and after a million hours and a 187 joints , we finally spent the money on carbon , took all that bullshit out of the room and hooked up one fan an one filter an strait out the roof and all problems solved.
and i believe gman went through all the same shit we did to come up with the same results....
we found a 6" 40 lb carbon filter on the net for 130usd to the door. so its not really that expensive.
If your just trying to get rid of the smoke smell in your living room then a small o3 generator will do a good job. just do not use o3 as your only means of ridding the stink in a stealth setup.
and yes o3 is very dangerous at higher levels. to plants, animals and humans.
