Researchers at Wageningen University are studying the effects of LED lights on the growth, flowering and fruiting of vegetable and ornamental plants in controlled environments.
Prof. dr. Leo Marcelis of the chair group Horticulture and Product Physiology was interviewed by the online magazine Urban Ag News about the lighting research being done at Wageningen University.
Marcelis explains that with the increased grower interest in LEDs, researchers at the university are focusing more of their studies on the effects of single and combined light wavebands on plant growth, flowering and fruiting. Most of the research that is done on lighting is with LEDs. High pressure sodium lamps are still the standard for most growers so the lamps are still relevant. But for research there is not as much being done with HPS as with LEDs and the focus is more on LEDs. There are new opportunities created by LEDs and many questions are still unanswered about using LEDs. As growers start to put in new lights they are making the switch to LEDs. It is expected that more of that will occur in the coming years.
