Ive only grown inside, unless u count the one female i stuck into the ground as it was, four or five years ago, just to see how it would do without preparing the ground and without fertz or good soil. Well it lived but wasnt much of anything. Did you watch the brown dirt warriors's prohibition on youtube? you can see the size of holes he digs and so on and you can get a good idea of how much you will yield when done right.
