Caz Graham meets Andy Roe, self confessed tomato fanatic, at the huge indoor tomato farm he runs in Lancashire. Andy is the tomato production manager at Flavourfresh, which produces 2,700 tonnes of them every year. They're grown in large glasshouses, where individual plants can reach 15 metres in length, their stems intertwined above specially created grow bags. The company uses LED lights to enable them to produce tomatoes all year round. Caz also meets Dave Barker as he introduces pollinators and natural pest predators into the greenhouse, and joins one of the company's seasonal workers as they harvest the tomatoes.
