Here in California (Central Valley) we are only allowed 6 plants, grown indoors not outside, and out of sight. I guess this was to prevent others from stealing your plants and neighbors complaining about the smell, and the "bad elements" coming in through the neighborhood. Since commercial industry cannot really grab a foothold on where they can grow, they started using houses as grow farms (really, the county won't let them, the city won't let them, where do they grow???) Now if your really far away or apart from neighbors or other people, then what is the issue??? I have seen here on the news of big busts occurring just because of this issue. WHAT WILL FIX THE PROBLEM???
Supplying yourself is one thing ( do you really need to swim in a pool of buds?) but to have massive grows, you are doing it for others medicinally or for recreation, but you are doing it in the wrong places!!! While it may be nice to grow monsters outside, I do just as well indoors with no one bothering me.
