THE LATESTon lighting

摘要

Lighting research is very exciting these days, with manipulation of LED placement and wavelength both possible. We checked with three leading greenhouse lighting researchers to hear about their newest studies - some ongoing and some recently completed, some new and some building on previous studies.One of the projects of Dr. Youbin Zheng, associate professor in the University of Guelph's School of Environmental Sciences, has the goal of determining the best light spectral combinations and intensities for indoor/warehouse and greenhouse microgreen production. This study, supported by the National Research Council (NSERC) and Greenbelt Microgreens, involves investigation of both yield and quality (for example, nutritional value and post-harvest shelf life).
