Protecting the A/B split through post-harvest, not just total flower recovery. The second, harder layer of yield.
Glossary
Grade preservation is protecting the A-grade share of recovered flower through drying, trimming, sorting, and handling. It sits alongside total recovery as the second, harder-to-measure layer of yield.
Recovery percentage alone can hide the real economic story: a line running 78% recovery with heavy A-to-B downgrade produces less revenue than a line at 74% recovery that protects A-grade.
Yield is not only how much flower you recover, it's how much grade you preserve. The producers who measure both are the ones with predictable margins.
