Greenhouse Production Research (GPRG)

The GPRG mission is to conduct fundamental and developmental research on production technologies, diseases, pests, and abiotic stresses for the greenhouse ornamental industry while safeguarding environmental quality, food, and worker safety. To transfer that technology to the industry through partnerships with state extension service and direct stakeholder interactions.  Please visit the GPRG home page or click on one of the links below to view our past and current involvement in these areas:
