I could live in Texas and grow 14958956893593 plants and never get caught. I really don't care "where it's happening" because the laws that are on the books say so.
You can argue that it "never happens" but the fact that it is STRICTLY ILLEGAL with PENALTIES OF 1-3 YEARS IMPRISONMENT for having 7-30 plants is obscene.
And the truth behind that is that anybody wanting to grow more pays to play, goes with the med card routine & extended plant counts. Various municipalities have constraints on that, but it's not something they put you in jail over.
