Interesting way to look at it, I agree but it's about numbers right? There's probably LESS of a chance that a neighbor is going to smell it, know what it is, and figure it's the person above, I THINK. LOL Nothing scientific to add but that's how I'd look at it. You are increasing your chances of getting caught, that is all. I'd say, keep going but save a little of what you save on street prices so you have $5,000 for your lawyer so that they will get you out of jail if you get caught.... Or if you are a trust fund kid, get one on retainer LOL
