The legacy 60°F / 60% RH drying protocol. Still workable in skilled hands, but a poor fit for modern flower and trim automation.
Glossary
60/60 refers to the legacy cannabis drying protocol of 60°F and 60% relative humidity. It can produce excellent flower in well-controlled rooms with skilled operators.
60/60 predates modern bud density, modern microbial thresholds, and modern trim automation. Denser flower struggles to shed moisture fast enough at 60% RH, and the pliable leaf slows trimmers (human and machine).
The 60/60 standard isn't broken, it's dated. The protocol landing across mature markets pulls harder on moisture in the first 48 hours, then finishes drier (around 57% RH) to feed automation.
