Custom LED Lighting in Future Plant Production

Research by ASTREDHOR shows that altering the natural light spectrum with specialized filters in production shelters improves horticultural plant compactness, branching, flowering abundance, and timing. Monochromatic LED modules offer additive spectral control to meet diverse production objectives and represent an energy-efficient alternative to traditional high-pressure sodium lamps, whose emission is suboptimal for photosynthesis. Trials in greenhouse potted crops revealed limited benefits under prevailing natural light, while fully enclosed environments like plant factories exhibited pronounced plant responses to specific LED light recipes. Collaborative tests under soilless and glasshouse conditions aim to refine spectral strategies for commercial horticulture.
