Dr. Erik Runkle of Michigan State University used the SQ-313 line quantum sensor mounted on a cross bar (as shown below) in greenhouse experiments controlling the flowering of Phalaenopsis Orchids. In the experiment the SQ-313 was used to measure photosynthetic photon flux and the daily light integral at plant height for both natural and electric light sources, while temperature was experimented with to control flowering.
