We have created a Vapor Pressure Deficit monitoring device unlike any other. It consists of a “sensor module” which should be placed 1mtr above the canopy with a built-in leaf temperature sensor.
And a display unit is connected to the sensor unit using a UTP cable so you can finally monitor the VPD, true ambient & leaf temperature, humidity, air pressure and your plants’ vital signs.
Vapor Pressure Deficit measures Plant Vitality!!
