In winter, for almost all crops light is the limiting factor for production. In the search for the maximum use of the limited light in the winter months, it is important to convert the light into crop production as optimal as possible. In order to improve, the knowledge gained in the project “verbetering lichtinval winterlicht”, where natural light entrance of the greenhouse roof for the winter period was optimized, in this project the scope was on the crop itself. The work in this project has been funded by the research program Kas Als Energiebron. This research program is a cooperation between the Ministry of Agriculture, Nature and Food quality and LTO-Glaskracht Nederland. To maximize light interception by the crop, an east-west oriented crop direction is the first step. The characteristics of the chosen cucumber variety, due to the variation in leaf size during cultivation from large to small leaves, require adaptation of crop management to the change in plant shape. A narrow trough distance showed a lot of damage of the crop. The best results were shown by the biggest gutter distance.
