i'm surprised at the lack of attention to physical security in so many of these cases.
I suppose for a personal grow of 4 plants or so it'd be difficult to secure, but if you have a large commercial grow op, you should also have a vault door and concrete egress walls.
I don't grow (shitty state), but I do keep my meds in a large national safe with my guns, the whole shebang anchored into the concrete, armed with relockers, etc.
At a bare minimum get a sentry safe and some 8 inch lag screws!!11
Oh, and of course a couple readily accessible firearms out when you're home. Remington 870 and legal semi-auto Kalashnikov with 40+ round mags would be a good start. Sucks that's how it has to be but people are assholes
Of course, the greatest ROI for being quiet is your best strategy of all
