I used to not use anything for smell.. But now with the blueberry x skunk#1 we had to use something...
Running 4,000Watt with 28 Plants 2 recirculation systems the lights are vented threw an 8" carbon filter and the stand up ac exhaust port is vented threw a 6" carbon filter. Both are vented into the attic and there is zero smell of MJ anywhere. Also have 8 or 9 of thoes timer air wicks that shoot a spray every 18 minutes all around the house.
