People who rent on entire house is more than likely to get caught for a few simple reasons. For one, they rented it, so that means the landlord can knock on your door anytime for a visit for various reasons...that brings me to the next part: A knock on the door, no one is home, except Mary Jane, unlock the door and walk into a stinky garden. The next dumb part is, it's a house, and if they used this house to grow nothing but cannabis in, you have to imagine the amount the lighting they had to use, and the amount of electricity produced. An electric company will notice huge electric bills and will be suspicious, and stealing it will not work either. It is easily tracable.

You are down the road, so who cares.
