Edward had a comment on the last post about another urban farming idea that is even better than the two that I had posted. I think all three of them have benefits, but the Omega Garden seems to be the best. If you had the Omega Garden on every floor of a tall building you would have a considerable amount of farming space. I'm curious to see which of these ideas, or a combination of them, will turn out to be the future of farming. Here is a short video on the Omega Garden. Thanks Edward.
