Curing is the final post-harvest step: dried buds are sealed in containers (usually glass jars) and opened periodically while moisture redistributes from the core to the surface and slowly declines. Over weeks, residual chlorophyll and starch break down, and harshness and grassy notes fade.
In practice
House position: curing is slowly reducing moisture content over time, not holding it constant. A steady, slow decline gives the best product. Targets are about the bud: water activity around 0.55-0.65 and a moisture content of roughly 10-12% w/wbeing reviewed, checked by equilibrated jar RH, stem snap and weight loss.
A typical approach:
1. Jar when small stems snap. Fill jars about three-quarters, loosely.
2. First week: check daily. Burp if equilibrated RH sits above about 65%; take buds out to air if far above.
3. Weeks 2-4: open less often as RH steadies in range.
4. Keep jars dark and cool, about 15-21 °C (60-70 °F).
Two to four weeks is a solid cure. Longer helps within reason.
Don't confuse with
- Drying: removing most of the water, before the cure.
- Storage: keeping a finished cure stable.
- Water curing: a soaking method (Contested, not recommended).
Myth check
A cure will never fix a bad dry (house position). Hay smell from bacteria, over-drying or drying too fast never truly comes out. Humidity packs rob terpenes; they are a marketing gimmick. See curing and burping.
An airtight container, usually wide-mouth glass, used to cure and store dried cannabis; ideally filled about three-quarters and kept dark and cool.The amount of water in a material as a percentage of its weight; cured cannabis flower usually sits around 10-12% w/w, though measurement method matters.A 0-1 measure of how freely available the water in a material is; for dried cannabis flower the accepted range is about 0.55-0.65 aw.A drying check: when small stems snap cleanly rather than bend, buds are usually dry enough to trim or jar for curing.Relative humidity is the water vapour in air as a percentage of what it could hold at that temperature, so the same RH dries plants differently at different temperatures.A grassy, hay-like aroma in dried cannabis caused by drying too fast, over-drying or bacterial activity; in GenetixBay's view it never fully cures out.A salt-solution sachet sold to hold a sealed container at a fixed relative humidity; GenetixBay regards them as a marketing gimmick that robs terpenes.Terpenes are volatile hydrocarbon compounds built from five-carbon isoprene units; in cannabis they are made in the trichome heads and are a major part of aroma and flavour.Briefly opening sealed curing jars to release moist air and let fresh air in, so moisture keeps declining slowly during the cure.The relative humidity of the air in a sealed container once it has stopped exchanging moisture with the material inside; ERH / 100 equals the material's water activity.
