Tunnel visionaries

Our Bandstand Beds gardeners were thrilled to get tickets for a tour of Growing Underground, to witness for ourselves the amazing food production happening right beneath our feet in in a tunnel in Clapham.

Visionaries Steven Dring and Richard Ballard

Our adventure started with a warm welcome from Richard Ballard, the co-founder of Growing Underground. He then went on to explain why he had decided to create a ‘vertical farm’, a method of producing food using hydroponic systems and LED lighting to grow micro greens in an ecologically sound and sustainable way. Being sited beneath the ground, the crops are not affected by the weather or bugs. So, no nasty crop spraying is required either!


What we were about to see

After our initial introduction to ‘all things underground’, we descended 100ft down a spiral staircase into the tunnels, built as deep-level air raid shelters during the Second World War. There are three such tunnels locally, at Clapham North, Clapham Common and Clapham South. But when they were built, who’d have foreseen that one of these tunnels would become a farm. And before we could see this futuristic concept, we needed to be properly attired…

Don’t we look fabulous!

As we began the tour Richard told us the history of Growing Underground, which 2013 trialling their farming techniques in the tunnel at Clapham North. It later moved to the Clapham Common site as it’s better suited for their needs. They now employ 22 people and the business is growing as fast as its product. Although currently only operating in a proportion of the tunnel they want to expand into the rest of the space over the next few years.

Preparing for germination

As we walked around the tunnel we could see a seamless manufacturing process has been set up. Seeds come in, they are washed and then planted in special trays stacked on top of each other like bunk beds. All lit by special LED lighting, powered by renewable energy.

The seeds germinate and grow quickly under the 24-hour lights, so quickly in fact that they can be harvested within one week, and freshly bagged for sale. This allows up to 60 crops a year as opposed to say one a month in the growing season above ground.

The temperatures in the tunnels can remain constant as it’s deep underground, which is another huge plus point. Typically the main produce is pea shoots and micro greens. And because the farm is in central London, crops can be picked and delivered quickly to the local or other shops across the capital. This means they also have a longer shelf life.

Ready to eat!

At the end of our tour we were lucky enough to try some of the product and were all amazed at how lovely it all tasted. To top off what had been an amazing experience, Richard then gave us all a fantastic bag of Growing Underground salad to take home for our tea.

Overall, we all had a fascinating and insightful evening visiting the ‘farm below our feet’. And it’s an amazing think to there are thousands of people going about their daily business along the streets of Clapham oblivious to the fact that 100ft below them a sustainable farm is ambitiously growing the crops of our future.
