Bosch Fruits is a 1.3 hectare blackberry farm in Berkel en Rodenrijs. The company has been cultivating blackberries since 2017 and started experimenting with supplemental lighting early on.
The challenge was to find a lighting solution that would allow for a year-round blackberry harvest. To do this, a lighting system had to be found that would not emit too much heat for the temperature-sensitive blackberries, but at the same time provide enough light to penetrate the dense plants sufficiently.
Ushio (formerly BLV) supplied an HPS TL toplighting system with an output of 150 µmol which remains switched on up to 18 hours a day during the darker period. In addition, several rows of shrubs were additionally equipped with LED IL interlight to test the effectiveness and possible advantages of a hybrid system.
