Don't think it can't or won't happen to you. Prison is full of people who thought that. Circumstances beyond your control can get you busted.
A few years ago, my house caught on fire, wiring issue in the basement. By the time I smelled smoke, the fire was roaring along, far too large for me to stop. I wasn't growing anything then, but imagine if I were. I'd have been busted because of some shitty luck and random chance, not because I blabbed, not because it was an apartment instead of a house, not because of foot traffic. I did nothing at all wrong, and yet...I'd be in prison now if I'd been growing anything then.
