It is as simple as harvesting 10 or 15 1LB plants yes, easier said than done though, someone will tell you but don't you need to grow 4 or 5 for each one you harvest to allow for police, thieves, animals and other losses?, so now you need to find somewhere to grow 60+ plant's, already getting harder just typing it!, i suppose if i needed x amount of cash i would be prepared to put the work in because believe me you will have earned it, whatever you get. As for strain, with a few exceptions almost anything outdoor should get you your pound if planted out early and given a good veg time.
