Here’s a remarkable american family that produces food, fuel and good living on a fifth of an acre home garden in the city. Pretty remarkable that the limited space being farmed produces enough to move off the grid. If this can be done with in-ground gardening imagine how much easier the effort might be with a bioponic for frequent cultivating, heavy feeder plants. Saving the ground for slower growing, less maintenance requiring fruit trees and shrubs, and small farm animals. It can be a good life, especially knowing if the price of gas goes up there will always be food on the table.
