On this week’s episode of the Cannabis Cultivation and Science Podcast, host Tad Hussey sits down with leading horticulture professor Dr. Youbin Zheng from the University of Guelph in Ontario, Canada. Dr. Zheng is a principal investigator at the absolute forefront of high-THC cannabis agronomy and the author of the definitive textbook, Handbook of Cannabis Production in Controlled Environments. Drawing directly from peer-reviewed data conducted inside commercial licensed facilities, Tad and Dr. Zheng smash some of the industry’s most deeply rooted legacy myths. They dive into why heavy phosphorus feeding is reducing your profits, the surprising truth about how modern high-THC genetics react to supplemental UV light, and the exact science behind using controlled deficit irrigation to trigger a late-flower cannabinoid spike. Whether you are managing a large-scale commercial facility or navigating a boutique organic living soil bed, Dr. Zheng’s pragmatic, data-first approach offers actionable insights to dramatically optimize your canopy’s ROI.","meta_description":"Can a simple 1-hour change to your lighting schedule increase your flower yields by 50% and your THC by 9%?
