I wish there were more people doing this with hydroponics or aeroponics, because gardening in dirt is super inefficient in terms of water and space usage. You also have to worry about yields, pests, and crop failures, which can be totally negated in a controlled environment. With GMOs (Perhaps with crops that are engineered to use more efficient C4 photosynthesis), and a finely tuned system, I imagine a person could survive on 500 square ft. or less.
