after awhile the smell to u is gone .......u will only smell it when u enter/leave the house .....nose blind
your only issue with u venting into the room like that is everything u own will set off dogs (this happens anyway from oil transfer) but u will set off a drug dog like u are carrying 5 lbs of weed
i been pulled over the dogs go off like crazy and the cops search my car for 40 mins find nothing .......the cop walked up to and said i never seen a dog hit like and us find nothing what are u doing bathing in the stuff
that is the only drawl back but it is going to happen to u anyways from the oil transfer i been growing for 3 years everything i own will set the dogs off now
here this thing is great ......it is a air filter with 5 parts but the most important one is Ozone

order one of those and keep it outside your room ........when u have ppl coming over run it for 20 mins and it removes the smell (i cut and jarred a half pound one day and then buddy calls saids is coming over in 20 mins ........i kicked that thing on put the stuff back in the negative pressure room and he could not smell shit .....if he did would of been all over me for free stuff )
but u will be fine on a passive intake on the tents then a small 4 inch booster fan in the top to remove the oxygen/heat dumping into the main room then dumping ( this is what i am currently doing myself ........exhaust outside is 1 6inch 400cfm fan with 2 tents in there 1 with a 6inch booster other is 4 inch booster.......running 1800w of led t5 now and then to start plants )
your houses ac should be more then enough to control it but if u need more a 5000btu window shaker will work ( my house is set for 76 cools to 72 ) my area is running 75 to 82 f
