My neighbors continue their behavior even when I'm not smoking at all. I took a tolerance break for a whole week, and they just continue doing what they do. I do have carbon filters and a vaporizer and it doesn't matter. As I said before, it's the fact that I'm legally allowed to get high that pisses them off, period.
I should point out that I grow my own in a small tent in my bedroom with zero smell. I only mention this because I would really like to move into a new place where I can continue to grow. If anyone in the LA area has suggestions, please PM. I would love to rent space in a house with other growers. Just putting it out there...
It's possible that what you're calling "zero smell" is the issue. I know for a fact that my grow room smells up my house. But I dont perceive it.
Can they hear vibrations from running equipment such as pumps or fans?
