Good morning friend!
Alright…. I think I got this thing figured out. The Cannatrol uses not only temperature and humidity levels to bring the moisture down…. But also the barometric pressure inside the unit to bring the moisture out, evenly.
That’s why the need for a refrigerator…. They needed that super tight sealing door, so they could adjust the pressure within the unit. Vapor Pressure Differential…. Pretty cool…
