In this episode Aleks and Alan interview Conor about vertical farming. Conor has built his own prototype vertical farm to grow wheatgrass and recently visited Growing Underground an underground vertical farm in London! We ask Conor what is vertical farming? How much would crops produced from a vertical farm cost? And how much produce can we get with a vertical farm compared with traditional farming? With the threat of an unstable climate and the formation of megacities is vertical farming the future of farming?
