I grow for myself and some friends and 4 plants provides PLENTY of bud. I can legally have 12 plants here, and I've grown as many as 6 at once, but I dropped back down to 4 because I had way more weed than I knew what to do with. I have close to a pound on hand here at any given time.
In today's world, saving a whole bunch of cannabis for the purposes of possible bartering would be a wise idea. After my bud is cured in jars long enough, I bundle it with my vacuum sealer into 1, 2 and 4 ounce bricks and throw them into the freezer. I'm hovering about 10lbs stored currently. Been saving for a while, but it adds up when you harvest every five weeks
