Farming entrepreneurs Kate Hofman and Tom Webster grow local sustainable food using a low-impact agricultural technology called aquaponics. The technology is a closed-loop farming method that combines hydroponics (cultivating plants in a water solution without using soil) and aquaculture (the farming of aquatic organisms).
Last summer, the two London based experts launched a demonstration farm as part of the Chelsea Fringe Festival. The project, entitled GrowUp Box, represents a unique urban farm concept based on two components: a fishing farm housed in an up-cycled shipping container and a greenhouse on top. In the shipping container Kate Hofman and Tom Webster raise tilapia fish, while inside the greenhouse as many as 400 salad and herb varieties can be grown at one time.
GrowUp Box was designed to be almost entirely self-sustaining with only minimal input needed. The nutrient-rich waste water from the fish tank fertilizes the plants above, while the plants purify the water pumped back into the tank. For a more sustainable form of food it is recommended that the fish are fed vegetarian protein.

GrowUp Box was built with the help of over 300 supporters and a successful Kickstarter crowd funding initiative (£16,500 raised).
The system can be adopted by any UK resident who wants to raise fish and grow plants easily in the backyard.
