How do I get the most consistent results?
First, make sure you operate the Purpl PRO according to its instructions—they’re fairly straightforward but must be done carefully as the Purpl PRO is still a scientific testing device. Grinding a flower sample is critical to allow proper homogenization of the sample. It is also crucial that seeds, stems, or other non-flower material be avoided, and that the sample chamber is properly filled before compressing with the cap. Beyond these basic setup tips, it is expected that results may vary +/-~2% between readings, which is the error of the predictions.
