Extensive research by Dutch students who were trying to reduce climate control costs in greenhouses bore fruit when their findings were used by horticultural companies in the Netherlands trying to keep energy costs down. In a massive greenhouse, home to one of the oldest and largest lily cultivators in the Netherlands, pink lights on the ceiling are trained on rows of green pots. The lights gradually brighten and dim, mimicking the cycle of sunset and sunrise. Experts say variable lighting has vastly improved the quality and yield of the pink and white flowers, and has also reduced energy usage compared to traditional high-pressure…
