Vertical Farming

Vertical Farms are a relative a new concept in architecture, the original idea from the New York Columbia University teacher Dickson Despommier. The main idea is to create vertical farm buildings in the cities avoiding the waste of CO2 emission created by the transport of food to the city, another advantage of the Vertical Farms are, use of eco-friendly energy like wind energy or solar energy. The ability to produce food all the year around like in a greenhouse. The production will not suffer from countryside for drought or flooding. Lees water consumption and saving in production and transport.
The last year Loft London Farm Tower Awards have very interesting project to build over the Thames River even still looking a bit futuristic and they seem rather expensive.

Anyway Sweden has taken note and is already building the first Vertical Farm in Linkoping and seem that will be ready in about over a year. The Plantagon Greenhouse dramatically change the way we produce ecological food. The Plantagon Greenhouse cut costs and environmental damage by eliminating transportation and delivering directly to consumers in city areas. The basic idea is to grow vegetables in pots in a vertical building. The pots are then put into trays, which are transported around the growing helix where the cultivation takes place.

The trays are equipped with a light sealed nutrient solution reservoir, and the pots are irrigated about three times per day using an ebb-and-flow technique. A capillary mat at the bottom of each tray protects the individual plants from drought. Excess nutrient solution is collected and reused after disinfestation.
