We have a friend, who is a professional indoor grower, manage some of his outdoor crop on our property. With 3 MMJ card holders, we had a total of 18 plants. They did really well until rabbits started gnawing on the stems. We put some fencing around the survivors and he had quite the yield. Huge plants. He gifted some of the crop - it seemed okay, though not great. It didn't hold a candle to the indoor stuff.
Once our son became conscious of the proliferation of MMJ in Boulder - stores and newspapers - we discontinued growing. He never noticed the plants in our yard though. We have an acre and it was well hidden.
Our house is way too small to grow indoors.
