Samenvatting

In recent years, electricity consumption in greenhouse horticulture has increased rapidly due to increasing areas of lighted cultivation and the increase in installed power. However, the rise in energy prices at the beginning of 2022 has made it clear that the trade-off between costs and revenues with respect to lighting has a major influence on the choices in purchase and use of lighting. LEDs are essential in the development of sustainable, fossil-free cultivation systems, due to their high efficiency. The transition to LED lighting is a system change: replacing HPS with LEDs has consequences for the energy balance of the greenhouse, morphology and physiology of the crop, and other factors such as crop health. This report outlines which development paths there are with regard to LED lighting, where we stand on these development paths, and what challenges there are still in the development of knowledge about the use of LED lighting in a fossil-free, sustainable cultivation system for tomatoes.
