Formal agronomic backgrounds are uncommon amongst cannabis growers in the United States due to the long-standing federal illegality of cannabis. Our Canadian neighbors federally legalized cannabis in October of 2018, opening the door to a new age of cannabis research in North America.

Youbin Zheng, Environmental Horticulture professor at the University of Guelph, stopped by FOHSE HQ to speak on his background, how legalization has impacted his research on cannabis, and how cannabis responds to light intensity. We also uncover how nutrient composition leads to pH fluctuations in the root zone, how spectrum plays a role in plant morphology, and much more!
