VPD Calculator for Drying Cannabis

To dry under ideal conditions, based on the studies and information I could find, you want to be between 0.8kPa and 1.1kPa to not dry too fast or too slow.


Ideally you want to be below 21c/70f to avoid evaporating terpenes.


It seems like you can go a bit above 21c and the difference to terpenes will be minimal. Based on the studies on terpenes it also seems like the evaporation point is different for each terpene. The most sensitive ones start evaporating at 21c/70f but a majority don't evaporate until 38c/100f.
