What is VPD?
Vapor Pressure Deficit (VPD) is an indicator of the evaporation potential of water to the air. It’s a measurement that’s defined as the difference, or deficit, between pressure exerted by the moisture present in the air currently and the pressure at saturation. It’s one of several different methods that you can use to evaluate crop stress or water stress within a plant.
