World's first underground urban farm is about to sell its produce

Peas, celery, parsley, and a variety of lettuces are growing in an old London WWII bunker 100 feet underground. To enter the 2.5 acre farm you must first wind your way down a 129-step spiral staircase near the Clapham North tube station. Once inside, you will see a sophisticated indoor farming system that will produce food consistent in flavor and color.

Crops will be grown in a sealed clean-room environment with a bespoke ventilation system, advanced LED lighting and a sophisticated irrigation system that enable the farm to produce crops with very little energy. 

The farm is pesticide-free, uses very little energy, and makes very little impact on the environment. The project, called Growing Underground, was hatched by Britsish entrepreneurs Richard Ballard and Steven Dring, who at first raised capital via crowd-funding, and then got two-star Michelin chef Michael Roux Jr on board as a backer. The farm will begin selling to Covent Garden buyers in just a few weeks.
