If you had 3 minutes to explain Vapor Pressure Deficit (VPD), where would you start? In this short video, Front Row Ag’s Tyler Simmons breaks down VPD in plain language. What it is, how it connects to relative humidity, and why there’s a “Goldilocks zone” that maximizes plant water and nutrient uptake. You’ll learn how air moisture levels create suction forces that pull water through the plant, how stomata react under stress, and why finding balance between humidity, temperature, and airflow is key for consistent growth.
