HUMMERT'S HELPFUL HINTS: VPD = Vapor Pressure Deficit
VPD is the difference (deficit) between the amount of moisture in the air and how much
moisture the air can hold. What does this mean to you? With mist/irrigation controllers
like the Water Pro and the Water Plus, the VPD sensor will give the controller the air
temperature, humidity and simulated leaf temperature (Water Plus VPD). Using these
three factors the controller will adjust the length of irrigation “off” time. If the air is hot
and dry, VPD will be higher and your “off” time shorter. Cooler, moister air lowers VPD
thus requiring a longer “off” time, which results in less watering or misting. You can even
set a different threshold for each zone
