This course examines the critical external factors that influence the growth, health, and yield of Cannabis sativa. Students will explore the impact of light, nutrients, pH, humidity, and vapor pressure deficit (VPD) on plant development while comparing indoor and outdoor cultivation environments. Emphasis is placed on understanding the role of integrated pest management (IPM) for maintaining plant health and the safe, regulatory-compliant use of pesticides. By mastering these concepts, students will gain practical knowledge to optimize cultivation practices and address challenges in diverse growing systems.
