<![CDATA[AUSTIN, Texas (Aug. 12, 2021)—PRESS RELEASE—Fluence by OSRAM, a global provider of energy-efficient LED lighting solutions for commercial cannabis and food production, announced today the results from a series of multiyear global studies analyzing the effects of broad-spectrum white light on cannabis, Merlice tomatoes and bell peppers.The studies found that while spectrum sensitivity is cultivar-dependent, broad-spectrum lighting strategies—which include green light and other wavelengths largely absent in narrow-band spectra—improved crop yield, morphology and overall performance in selected cultivars when compared to narrow-band spectra with high ratios of red and far-red wavelengths. “The results from our global studies show how effective broad-spectrum white light can be in improving crop performance for many cultivators around the world,” said Dr. David Hawley, principal scientist at Fluence. “Broad-spectrum strategies are about balance and flexibility in the spectrum itself as well as the overall cultivation approach. While there are certain scenarios in which narrow-band spectra, or pink light, may make sense from an energy efficiency or crop production perspective, we’ve found that many cultivars simply perform better under broad spectra across the KPIs cultivators care about most: yield, morphology and overall quality. Our latest research empowers us with new insights to assess each grower’s objectives, weigh those objectives against a facility’s unique financial, environmental and energy parameters, and then ultimately derive a tailored solution for each cultivator.”Merlice tomatoesA collaborative study with Wageningen University and Research (WUR)—led by researchers Leo Marcelis and Ep Heuvelink—evaluated differences in yield, morphology, development and quality for Merlice tomatoes grown with the VYPR top light series under four light spectra: PhysioSpec BROAD R4, PhysioSpec BROAD R6, PhysioSpec BROAD R8 and PhysioSpec DUAL R9B. BROAD R4, R6 and R8 all contain significant fractions of green light and other photosynthetically active wavelengths, while DUAL R9B is a narrow-band spectrum that contains almost no…
