Research

GLASE has secured a $5 million investment to develop a multi-year holistic research program with more than 300 specific technical milestones ranging from new LED encapsulants and drivers to integrated greenhouse control systems implementation.

Working together, Cornell University, Rensselaer Polytechnic Institute and Rutgers University are combining complementary areas of expertise to design and develop innovative greenhouse lighting and control systems. GLASE-developed technologies will be implemented in small and large commercial greenhouses and become preferentially available to its industry members for licensing and implementation.
