The entrepreneurs decided to operate in the underground. Literally. The flower beds for the crops were set in abandoned London underground tunnels used during World War II as anti-aircraft shelters. Amazingly, these corridors were empty until last year and only London rats used them.
The Growing Underground crops are not disturbed by the lack of daylight. Sun rays were successfully replaced with LED lamps. The LED technology completely satisfies the demands of the plants, even with individual preferences of different plants in mind.
Gardeners decided to focus primarily on leaf vegetables - different varieties of salads and herbs: basil, rosemary, chives, dill and mint. The plants grow in a specially designed system of shelves equipped not only with lighting, but also with automatic irrigation devices. During and Ballard are happy to share their successes on the company website. You can cheer on them by watching photos posted there, showing plants at various stages of growth.
Now, this London garden is 550 square meters of underground with hydroponic crops. However, soon the annual harvest will be much greater than the current 20,000 kilograms. Another vast section of the so-far inactive corridors is to be added to the project - as much as 20.000 square meters.
