The use of pulsed light in indoor farming to reduce the energy consumption
In indoor vertical farms, energy consumption represents a bottleneck for both a system’s affordability and environmental footprint. A new frontier offered by LED technology is the pulsed light. LEDs can indeed be switched fully on and fully off in an extremely short time interval. By adjusting the frequency and the duty ratio, depending also on the type of cultivation, this technology provides the possibility to save energy, compared to the use of continuous light, without compromising the yield of the product.
