Light-emitting Diode Sole-source Lighting Effective in Bedding Plant Seedling Production
In northern latitudes, producers of bedding plants depend on supplemental lighting during the late winter and early spring growing seasons. Unfortunately, these peak times for young plant production are also the darkest. Researchers have determined that a minimum amount of photosynthetic light (daily light integral; DLI) is necessary to produce high-quality young plants in greenhouses. In ...
