Dry cannabis at 60 to 70°F with 55 to 60 percent relative humidity for 7 to 14 days, until small stems snap instead of bending, then cure the flower in airtight glass jars at roughly 62 percent humidity for 2 to 4 weeks, opening the jars daily during the first week. Those three variables, temperature, humidity, and time, decide whether your CBD flower keeps its terpenes or fades into a hay-like smell.
What are the ideal conditions for drying cannabis?
Aim for a dark room between 60 and 70°F with 55 to 60 percent relative humidity and gentle indirect airflow. Hanging whole branches slows the dry and protects trichomes better than spreading loose buds on a screen.
Cannabis Drying and Curing Methods: A Comprehensive Guide
- Keep a small oscillating fan pointed at a wall, never directly at the flower
- Skip heaters, dehumidifiers on high, and open windows with strong drafts
- Leave a little space between branches so air moves around every side
- Check daily after day five, since the last two days move fastest
How long does cannabis take to dry?
Most home growers land between 7 and 14 days. Wet-trimmed buds dry in about a week, while whole plants with stems intact can take two weeks or slightly more in cool, humid rooms.

Drying too fast traps chlorophyll and starches, which produces that harsh, grassy taste. Drying too slow invites mold, especially when humidity climbs above 65 percent for hours at a time.

When is cannabis dry enough to start curing?
Use the snap test. Small stems should snap cleanly, while thicker stems bend without breaking. Buds should feel dry and slightly crisp on the outside with a little spring when squeezed.
Confirm with a jar test. Seal a sample in a small jar with a hygrometer for one hour. A reading above 65 percent means the flower needs more drying time outside the jar.
How do you cure cannabis step by step?
- Fill clean glass jars about three quarters full to leave headspace for air.
- Days 1 through 7: open each jar for 5 to 10 minutes twice a day.
- Week 2: burp once a day for about 5 minutes.
- Weeks 3 and 4: burp every few days until the smell settles.
- Add a two-way humidity pack once the flower stabilizes near 62 percent.
Store the jars in a dark cabinet at 60 to 70°F. Shake gently during burping so buds do not compact into one block.
Why does curing matter for CBD flower?
Curing lets sugars and chlorophyll break down slowly, which smooths the smoke or vapor and rounds out flavor. It also protects terpenes and cannabinoids that degrade when flower dries too quickly or sits in open air.
Well-cured CBD flower smells sweeter, feels less harsh, and holds its potency longer in storage. The cure does not create cannabinoids, it preserves what the plant already made.
What mistakes ruin a cure?
- Jarring buds while they are still damp, which grows mold within days
- Overdrying until buds crumble, since that cure never recovers
- Storing in plastic bags or sunny shelves
- Skipping burping because the jar smells fine on day one
- Packing jars tight with no headspace
How should you store cured cannabis long term?
Keep cured flower in amber glass with a humidity pack, away from light and heat, and it holds quality for six to twelve months. Check jars monthly for condensation, and re-burp if you see any moisture on the glass.
