Eindhoven– Can LED lighting offer an economic way to bring fresh, locally grown cucumbers to consumers in the Nordics and Eastern Europe in the winter months? The answer is yes according to a recent growth trial carried out by Philips Horticulture LED Solutions, the leading provider of LED lighting solutions for the horticulture industry, and Warsaw University of Life Sciences, one of the top one hundred international universities in agriculture and forestry. The trial compared cucumbers grown under a) 100% LED lighting, b) a combination of high intensity discharge (HID) toplighting and LED interlighting and c) HID toplighting alone.
“The 100% LED compartment produced a 24.8% higher yield, used 1.4 less liters of water per kilogram, and reduced energy costs by 60%”, says Professor Janina Gajc-Wolska, Department of Vegetables and Medicinal Plants at Warsaw University of Life Sciences. “Consumers also preferred the taste of the cucumbers grown under 100% LED lighting, saying they tasted slightly sweeter and less watery.”
