Fluence’s Red Sandwich strategy is the result of five years of disciplined research into light intensity, spectrum, and distribution. By applying high-red spectrum light to both the top and bottom of the canopy simultaneously, growers can achieve system efficacy of 3.4 µmol/J — compared to roughly 2.7 µmol/J for standard white LED top-lighting systems.
The result: higher yields, better bud uniformity, and the elimination of photobleaching, without added complexity or energy demand.
Each insight builds toward a single goal: helping cultivators achieve more with every photon. Whether you’re optimizing existing rooms or planning your next facility, Red Sandwich showcases how red—when guided by science—becomes the most efficient color in cultivation.
