In some cities this is illegal, you can’t grow your own food, so check local laws, ordinances and zoning and if possible move to cities where it’s not illegal to grow your own food in your backyard. Don’t break their laws, their city ordinances and their zoning, 1 complaint by anybody for any reason and that’s the end of your own food supply. There are people out there that will go around trying to destroy people’s food supply cause they are SPs, their goals are to destroy human life, to destroy human beings including murder, when filing a complaint, their intent is to destroy the person’s food supply so they die of starvation, it’s an ops, and since the cities don’t disclose, expose who made the complaint, it’s covert ops. So to avoid this kind of corruption and abuse, move to cities where it’s legal.
