33 metres below the streets of South London there are huge tunnels filled with hydroponic irrigation systems, LED lights and thousands of thriving little seedlings. This is Growing Underground, a futuristic farm with sustainability at its heart. In this episode of Business Unusual, Claudia Winkleman talks to Steven Dring and finds out what it takes to make a success of such an unconventional idea.

Steven explains why a WW2 bomb shelter is the perfect environment for growing salads, how he and his co-founder overcame the bystander effect and what Raymond Blanc had to say about their fennel.
