Repurposing WWII air raid tunnels beneath the streets of London to sustainably grow herbs and leafy greens, saving energy and water.

Growing Underground (GU) is a commercial urban farm located 33 meters under the streets of Clapham, London in a converted WWII air raid shelter. GU utilizes the latest LED lighting and hydroponic growing systems to sustainably grow fresh herbs and salad greens year-round. Committed to reducing their carbon impact, GU's growing methods are powered by renewable energy sources and use 70 percent less water than traditional farming methods. Supplying local food service, retail, and farmers' markets, GU reduces the need to import crops and minimizes wasted energy from long-distance food transport. By staying local, GU's fresh produce is supplied in less time, reducing waste and most importantly, maximizing taste.

Growing Underground is no longer operating.
