Closer to few hectares if you want to be self-sufficient. Our greenhouse is 60m2 + vegetable garden around 200m2 + few dozen apple trees and some other fruit trees. The season is not very long here (NE Europe), so we basically start to harvest lettuce, radish and spring onions some time end of May and from that moment on we basically switch to "home grown" diet if you wish which lasts into late October or so. The part about tomatoes and cucumbers is very true. Once they start to bear fruit, you need to have your preservation or distribution plan ready or they will be wasted. That said, we have to visit supermarket weekly anyway...
