Glossary
Funk is a sour or musty top note that appears in dried cannabis when flower sits above roughly 60% RH during drying or 0.60 water activity in storage.
Funk usually clears compliance testing but fails the trained-nose test at the wholesale desk. Brokers in mature markets flag it on sight — one of the fastest ways to lose a repeat wholesale account.
Anything above 0.60 aw in dense flower risks funk, regardless of what ASTM's 0.65 upper limit allows. Hold the operating line at or below 0.60 for premium lots.
