#1 way is that the grower tells someone. Then either that person tells the cops, or that person tells someone who tells someone who tells the cops.
#2 way is getting stupid/sloppy. This includes odor control, light leaks, stealing electricity, leaving plants where they can be seen, driving while holding, growing in a place that isn't secure, etc.
After that comes just plain bad luck, such as police are chasing a burglar and he ducks into your house to try to escape and the cops stumble on your grow, something like that.
If you have a small personal grow that is buttoned up in a secure place and you tell absolutely no one then your chances of getting caught are extremely remote.
