Calculating moisture loss/gain in dry cannabis: what's the math look like for moisture flux?
Cannabis math time! I work with large masses of dried plant material and I'm trying to better understand moisture gain with regard to environmental humidity and temperature.
The specific problem would look something like this:
We have 9000 grams of dried buds that are kept at about 65°F and less than 50% RH. They are moved to a different environment that is less controlled (70-75°F and 50-65% RH.
Moisture content is measured at 12% in environment 1 and after a few hours it's at 14.5% in environment 2.
The rate of moisture gain is surprising to me, and I'm trying to understand if this is reasonable. Answers or resources to find the underlying math are appreciated!
