Frequently Asked Questions
Cannabis moisture testing measures both moisture percentage and water activity to help you dial in the cure. Getting these levels right helps preserve potency, prevent mold, and maintain flower quality through storage and sale.
Moisture percentage shows how much water is in the flower by weight. Water activity measures how tightly water is bound. Together, they give a clearer picture of shelf stability and mold risk than moisture alone.
The Purpl PRO is designed for internal quality control, curing decisions, and process checks. It is not a substitute for regulatory compliance testing, but its results are validated against certified lab methods.
Moisture and water activity measurements are verified against certified lab results using established scientific methods. This allows you to trust the data for day-to-day curing and storage decisions.
Each test takes about 10 seconds. There’s no sample prep beyond grinding flower, and results appear instantly in the app.
No. The Purpl PRO uses non-destructive near-infrared spectroscopy, so the same sample can be kept, processed, or packaged after testing.
