my experiences with growing weed is when you live with your grow you get Immune to the smell. and folks who do not grow or live around it can smell it much more then you can. if you have doubts get away from your grow for a week then come back and see if you can smell it. my advise if your in a none friendly pot state get a carbon scrubber .be leave me it will pay for it self .i used a can33 combo and all i did was buy the disposable cans with carbon for 6 years on at $120 a year. and some times a year and a half.
