Finder notes

  • Heavy myrcene load — skipped when next-day heaviness is a concern.

What these numbers are

These describe a typical example of this name across many growers. They do not describe any jar on any shelf. We checked 4,914 lab-tested samples from 1,950 growers: the highest terpene changes between growers for every cultivar we tested — about a third of the time for a name like Blue Dream, and more than half for some others. Here is the data. That is why these figures no longer drive our finder, and why we ask shops for certificates instead.
