I have been learning lately about vpd and i am experimenting with it with my current grow . I have an ir thermometer and a controller inside my tent which keeps temp and Rh strictly at the values i put. My question is this.
If the leaf temperature is higher than the tent temperature does it mean that my rh is too high and no transpiration occurs to cool the plant? Or the rh is too low which gets the lvpd higher and stresses the plant to the point that it does not transpire again?
