Farmers using hydroponics and LED technology to grow greens underground are ready to harvest their first crop
As German V2 rockets pounded London in the later stages of the second world war, one of the underground safe havens where thousands of people sought refuge was a tunnel system deep below Clapham High Street in the south of the capital.
Seventy years on, the network of tunnels is in use again but for an altogether different purpose: farming. Open the cage-style doors of the lift after descending 100ft below street level, and the modern-day visitor will find an underground farm.
