For my first couple of years I grew many (20+) plants in my basement and the whole house smelled like weed. Sometimes the worse was in late flowering & harvest, but sometimes in veg they created a lot of odor and when working on the plants too. Tried using candles, Ozium, and ONA with limited success. Candles are nice, walking around the house and spraying Ozium worked on occasions, having ONA in jars throughout the house was ok, but it was a pain in the ass, expensive, and the results were just ok.
When I created negative pressure in my grow rooms and exhausted the air outside the house almost all the odor issues were resolved, and could wear clothes that didn't smell like weed. The problem with not scrubbing the air was anyone coming to the house could smell it from the driveway much easier. Negative pressure with pulling air out thru carbon filter (Phresh) resolved 99% of odor issues.
ONA is used to address the 1% issue, only as a temporary situation when needed.
The problem is I have to exhaust air out all the time or odor becomes a problem So my exhaust fan run 24 hours a day while I'm growing.
