Artificial light for fruit and vegetables

At an early stage, researchers in Wageningen studied the use of artificial light for fruit and vegetable cultivation. With artificial light, cultivation can be intensified and crops can also be grown in light-poor winters. Because the conditions are controllable, the effects are easier to investigate than with sunlight. There are still questions about light utilization efficiency, the optimal lighting duration, the best light colors for crops and fruits, and so on. In the hypermodern Netherlands Plant Eco-phenotyping Centre, the light can be fully controlled and cameras and other sensors can register plant growth in detail.
