I just smoke on my drive with the gates closed, I wouldn't worry about your neighbors the person who lives next door to me is a cop but he never says anything lol
I mean you could smoke indoor as long as your next to a good air filter. Blow the smoke into it basically. My current 6 Jock Horror Autos, coco coir grow.
I've been here..and discovered 'water cured weed' simply soak you buds for 4 days(my preference) once harvested, then hang like socks to dry the water leaves the thc attached but seriously reduces the smell unfortunately the taste too can't win 'em all, but you keep the peace with those too close good luck
Just put some bounce sheets in a toilet paper roll and exhale through it. Covers the smell well. First grow using cfls.
I sometimes smoke in the bathroom and blow the smoke up out the vent fan ( most bathrooms have the fan) and leave the fan running afterwards. Another option imo is vape. Less smell.
