You can't hide it from the cops today, because of highly trained dogs.
Get real. The fucking cops are well-funded, well-trained, and get their rocks off on busting us growers...
Fuck them, but respect them as well...because they are a formidable opponent to us...
Keep a small personal grow, tell no one, and you will be OK.
But if you get greedy and try to grow large quantities and sell, then you will eventually get busted and lose your life savings in lawyer fees trying to stay out of 10 years behind bars getting butt-fucked every day.
