Get a 400 watt light and grow a bit, but don't involve the mother and her children. That'll give you a chance to practice on a smaller scale, give you some bud to smoke, make a little on the side. Wait until you DO get a bigger/better connection before you jump into trying to grow larger quantities. It's not really THAT bad of a plan, as long as you keep children, and the mothers the children rely on, out of the picture, and as long as you can find someone to take that kind of quantity off your hands on a regular basis. As long as you only have to deal with one person, you can stay quite inconspicuous, as long as you're not stupid with the money. (You will need to launder it thoroughly to avoid the penetrating gaze of the tax authorities, and avoid buying things that your legitimate income would not allow you to afford.)
