hey man
ona gel is not worth it the cost is recurring 60 to 90 days
like all the ppl have said it is about venting ..........if u are dumping the air outside tho a portable ac window vent attachment (it is this plastic form with a cut out to let the exhaust from the ac go out ....pull down the shade and it looks like a AC )
now to cover that up u just need the carbon scrubber works for 12 to 15 months then needs to have the active carbon replaced u can buy a new one or buy a refillable one and change the carbon ...............now if u are worried about it and want that extra cover they do make Ozone gen that can fit inside ducting but i only seen them in 8 inch and 10 inch duct sizing not the normal 6 inch ............as if u want u can add a wye duct want put a dampener to close off the end open it up and add in something smelly like laundry sheets (best thing to add is jasmine it masks the smell with dogs)
as for the room itself u can always air polish ..........this is basically a carbon scrubber hung in the room with a fan attached to it sucking from the room dumping back in the room always cleaning the air
the final step is to make sure u have negative pressure .....u do not want the air in the room to flow back out into the apartment ....should always be a draft sucking into that room ...................out side the room get one of these and run it when u need to

it kills any smell and clears out smoke in the air ............i can clip a hp in the room turn this thing on and in 20 mins smells like a hospital ......tested it with ppl that do not know what i do ........if they smelled something they would have been all up my ass about it i know risky test but it had to be done
ok dogs that are trained to detect it ...............u will always set them off u might not smell it or any other human but that dog will bark like u have 5 lbs on yah .......so this is something u always must rem if they say they are bringing dogs around and u have something on yah eat the shit or state u are in a rush u would like the cop to start writing the ticket if the dogs show up by the time it done then ok other wise u want to go on your way ............but if u are busted and know it say i want a lawyer and do not talk to anyone until the commissioner starts asking u basic ?s to set bail ...............this is the only down side to growing your own shit ........everything u own will be tainted with it at some point and time
