The
urban farm project Growing Underground is located in tunnels beneath the London
Underground's Northern Line that were originally built as air-raid
shelters during the Second World War. They produce nine
micro greens (plants that are harvested at the seedling stage ) and
three normal herbs. Intent
on demonstrating that it is possible to operate a commercial urban
farm with a minimal carbon footprint, the entrepreneurs plan to
transform 2.5 hectares of the disused air-raid shelter into growing
space that will supply produce to London businesses, reducing the
amount of food miles "from farm to floor".
