Growing Britain's growing: the Environment Secretary has been to Holland to learn about high-tech horticulture. We ask what British growers make of Ranil Jayawardena's £12.5 million of grants for automation in the sector. In the week when we're looking at international trade, we hear from one of the countries we rely on for fruit and veg: Spain. A drought this year and higher energy prices are having an impact on producers. We visit Cornwall where a multi-million pound project is retro-fitting 250 homes with ground source heat pumps. Presented by Charlotte Smith and produced by Beatrice Fenton.
