You can grow for personal use anywhere in the state. As far as i know no city's have outlawed personal use or growing. I believe the way A-64 is worded they cant make personal use or personal growing illegal only the business end can be opted out of and made illegal. A bunch of city's have opted out of a-64 as far as businesses go. Meaning no commercial growing or sales.
As far as to how much you can grow each person is allowed 6 plants with no more then 3 in flower at a time. They must be in a secure location so you can't just go out in your back yard and grow unless you have a green house that can be locked. The thing that would suck in your case is each person would have to have their own secure grow room or green house. So your plants must be separate from your wife's and sons and so on. Not sure how it will go with separate tents. If a tent was locked would it be considered secure under A-64. I guess time will tell on that one.
Having said that I really don't think small personal growers have much to worry about. There is a ton of folks growing for the black market here and they are more worried about them then busting small personal growers. Hope this helps
Edit: Forgot to mention that if you got a red card ( medical MJ ) the amount of plants you can grow for personal use goes up to 12 plants. Red Card prices dropped this year costs 35 bucks to file the application now
