UrbanFarmers is a small company that has developed a simple way to grow food on the roof: Take a standard cargo container, put some plants in a greenhouse on top of it and fishes in huge water tank inside the container. Meet the UrbanFarmers BOX.
The water is pumped to the plants for irrigation. It contains the wastes from the fishes which fertilize the plants. The plants clean the water which goes back into the fish tank.
Unlike other irrigation systems, this one has only a small loss of water. It needs no artificial fertilizers. There is no need for pesticides or fungicides because of the greenhouse. The fishes don’t need antibiotics.
