A curing jar is the sealed container in which dried buds cure. Glass is the standard: it is inert, gas-tight with a good lid, holds no odour and lets you see the buds. Wide-mouth jars are easiest to load and inspect. Other options include food-grade stainless or ceramic containers with airtight seals; thin plastic bags and porous containers lose aroma.
In practice
How to use them: - Fill to about three-quarters, loosely, so air can circulate and you can roll the buds when burping. - Add a small calibrated hygrometer, and read it only once the jar has equilibrated (several hours to overnight). - Label cultivar, harvest date and jarring date, and in trials the wet and dry weights. - Store dark and cool, about 15-21 °C (60-70 °F). Clear glass in light degrades cannabinoids; keep jars in a cupboard or use amber or opaque glass.
For long-term storage, once the cure is done, fill jars more fully to cut headspace and oxygen.
House position: no humidity packs. If a jar needs moisture, add a fresh bud.
Don't confuse with
- Humidity pack: a sachet sold for jars; GenetixBay doesn't recommend them.
- Turkey bag: a plastic oven bag used for bulk storage.
- Vacuum container: removes air but can crush buds.
