Brother I couldn't agree more. I despise ashtray smell. I despise cigarettes and the idea that my cannabis could cause my house to smell that way. Luckily I have a great source for my flower; myself. I am super clean in my grow and like you I use nothing on my plants. They are never sprayed with anything and I use more filters than you can shake a stick at. I also flush for 2 weeks then another 2-3 days during the constant dark that I end my plants with. Makes for some smooth clean smoke. Keep spreading the good word my friend.

Smoke it if you got it and go find some if you don't.

Peace,
The Last Sage
