Living in Minneapolis has many benefits, one being the plethora of farmers markets to choose from year round. One problem with the city though is the climate. Our cold winters mean I rarely find local fruits and vegetables after October and before May. While this might sound like a standard problem for northern cities, some are breaking the mold and growing crops year round. The logical answer is a greenhouse out on the rural fringe, however some cities are taking it to the next level. They are growing acres of crops on small city blocks. The answer they have found is a vertical greenhouse.
