What Does VPD Stand For?
VPD stands for Vapor Pressure Deficit
Vapor Pressure Deficit (VPD) is a measure of the difference between the amount of moisture in the air and the maximum amount of moisture the air can hold at a given temperature. It is expressed in units of pressure, typically kilopascals (kPa). VPD is an important parameter in climatology and agriculture, as it influences plant transpiration, water loss, and overall plant health. Managing VPD can optimize growing conditions and improve water efficiency in agricultural practices.
