Jimco is the fourth generation van Dijk at the family’s cucumber nursery. He runs the business with his father Sjaak. They both love to innovate in their individual areas of expertise. Sjaak is technically minded and has developed many new techniques to improve their energy management. “We were the first to install a cavity screen - this consists of two screens in a screen installation, 4cm apart - which insulates effectively and retains warmth”, explains Jimco. “This has significantly reduced the energy demand per square metre. We're incorporating a number of different methods in order to solve our energy issues.”
