Dutch greenhouse studying effects of variable spectra on peppers
Added on 29 January 2024
An ongoing Dutch study into the possible benefits of LED lighting on pepper cultivation is taking on a new dimension, as it will now also examine the effects of actively varying the spectra and intensity in conjunction with different irrigation strategies.
Delphy Improvement Center in Bleiswijk, The Netherlands has tapped a “dynamic” lighting system from Canada’s Sollum Technologies, citing Sollum’s “capabilities in zoning, spectral adjustments and automatic dimming.”
Sollum is known for its combination of lighting and controls that allow users to dial up varying light recipes in order to optimize the growth of different crops. The Montreal-based company provides the lighting schemes on a service basis, which it calls SUN as a Service (SUNaaS), such as at Canadian pepper, eggplant, cucumber, and tomato farm Proplant Propagation late last year.
Delphy is specifically examining the variable lighting on greenhouse peppers raised using different irrigation systems, as it seeks the optimal combination of lighting and watering styles.
"As we delve deeper into the realm of greenhouse LED lighting research, and especially the potential of growing pepper with LED lighting, the collaboration with Sollum provides new opportunities to develop our knowledge,” said Delphy Improvement Center manager Lisanne Helmus-Schuddebeurs. “Their dynamic lighting solution offers an adaptability that can improve the efficiency of lighted pepper cultivation. This collaboration will focus on understanding the interplay between dynamic lighting and irrigation strategies, aiming to provide clear and actionable insights for growers.”
