Lights that respond to current conditions eliminate the need for continuous grower input, simplifying the process and letting growers focus on growing, not on spending time in front of the computer. Photo: Signify LED lighting has come quite a long way in the past few years. What began as a simple energy-efficient replacement for high-pressure sodium (HPS) legacy systems has become a customizable solution to better yields, faster cycle times, and even higher energy efficiency. While work is still being done to improve the efficiency of turning electricity into photons, that&rs...
