The glasshouse will be placed on top of a shipping container adapted to house tanks in which tilapia fish will be raised. Waste water from the tanks will be recirculated to fertilise the salad and herb plants, which in turn will clean the water for the fish.
The polycarbonate glasshouse from UK supplier Naturelight features a fully opening roof, whose panels can open and close in one minute, either by manual control or automatically in response to temperature, humidity or rainfall levels or wind speed.
The "vertical farming" installation is the work of urban farming business GrowUp. It will form part of the Chelsea Fringe Festival, which runs from 18 May to 9 June, and remain open to the public throughout summer.
A company representative said: "This is just the beginning - we want to take large, unused spaces in the city, such as rooftops or brownfield land, and transform them into sustainable commercial farms using the type of technology showcased in the GrowUp Box."
