Global research results on broad-spectrum lighting strategies for cannabis and food crops

Fluence by OSRAM (Fluence) accounces 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.

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, the company found that many cultivars simply perform better under broad spectra across the KPIs cultivators care about most: yield, morphology and overall quality.
