How to Tell the Cure is Done for Smooth Potent Weed Every Time
Know exactly when cannabis curing is complete: 3 finish-line signals, the 24-hour jar test, and quality markers that guarantee smooth, potent results.
Written by Sipho Sam
December 5th, 2025
Properly cured cannabis delivers three unmistakable signals.
The smell evolves from hay or fresh grass to a rich, strain-specific aroma with no trace of ammonia.
The exterior feels dry while the interior springs back slowly when you squeeze it.
The smoke burns evenly to light gray or white ash without harsh throat irritation.
Your jars should maintain a steady relative humidity of 58 to 62% without significant fluctuations.
The 24-hour jar test removes guesswork by giving you exact readings and specific actions for every moisture level, whether you're finishing your own harvest or evaluating flower you purchased.

What a Finished Cure Looks, Feels, and Smokes Like
A finished cure produces cannabis with strain-specific aroma, springy texture, and white ash when burned.
The smell progresses from chlorophyll and grass clippings to a neutral sweetness, then, by week two or three, you catch the strain's defining notes: citrus, pine, fuel, berries, and earth.
A properly cured jar releases aroma the moment you open it.
Ammonia is your emergency signal.
That sharp, stinging smell like cleaning products means anaerobic bacteria from excess moisture.
Pull those buds immediately and spread them on a screen to dry for several hours.
Gently squeeze a bud.
The outer layer feels crisp, but the core has moisture that makes it slowly expand back over two to three seconds when you release pressure.
It shouldn't crumble like overdry flower or feel damp and sticky like under-cured material.
The burn test proves everything.
Properly cured cannabis burns evenly with light gray to pure white ash, showing chlorophyll has broken down completely.
Black, clumpy ash means the cure wasn't finished.
This white ash test is what Mood uses to verify every batch before shipping.

The 24-Hour Jar Test That Removes Guesswork
The 24-hour jar test measures relative humidity to determine exact moisture content and tells you precisely what action to take.
This diagnostic removes guesswork about whether your cure is progressing correctly or heading toward disaster.
Fill a clean mason jar about 75 % full with your drying buds without packing them tight.
Seal the jar completely and set it in a cool, dark place.
Leave it alone for exactly 24 hours.
No peeking or burping.
You need a closed system for accurate readings.
After 24 hours, open the jar and check your hygrometer with your drying buds.
Don't pack them tight.
Seal the jar completely and set it in a cool, dark place.
Now the hardest part: leave it alone for exactly 24 hours.
No peeking, no burping.
You need a closed system for accurate readings.
After 24 hours, open the jar and immediately check your hygrometer reading.
The number determines your next move:
70 % or higher: Too wet.
This is emergency territory.
Remove the buds immediately and return them to drying on a screen or rack for 12 to 24 hours.
Moisture above 70 % invites mold development within days.
You're not ready to cure yet.
65 to 69 %: Slightly elevated but manageable.
Leave the jar open for two to four hours to let excess moisture escape, then reseal and test again tomorrow.
You're close but not quite in the safe zone.
60 to 62 %: Perfect.
This is your target range.
Begin the standard cure protocol with daily burping during week one.
Moisture is balanced, and mold development stays minimal as long as you maintain proper burping.
55 to 59 %: Slightly overdry but salvageable.
The cure will still work, though it may take longer to smooth out the smoke.
If you're below 57 %, consider very light rehydration by placing a small humidity pack in the jar for a few hours, then removing it and continuing the cure.
Below 55 %: Overdried.
You'll need controlled rehydration to bring moisture back up before continuing the cure.
The terpenes you lost during that too-fast dry won't return, but you can still improve smoothness with extended curing.
One critical warning: don't add humidity control packs during the first two weeks of curing.
They can mask problems by maintaining 62 % humidity in the jar while the bud cores sit at 70 %, breeding mold from the inside out.
Save those packs for long-term storage after week four, once moisture has equalized throughout the bud.
Managing Weeks One Through Four Without Mold or Overdry
Curing is the final phase of moisture management where chlorophyll breaks down and terpenes develop.
Start when small stems snap cleanly after 7 to 14 days of drying at 60 degrees with 60% humidity.
Week one: Burp jars daily for 5-10 minutes.
Opening the jar does more than exchange air.
As you open it, moisture that migrated from bud cores to the surrounding air escapes, pulling more from deep inside the buds.
Watch for an ammonia smell (spread buds immediately if detected) or no noticeable change in smell (possible overdrying).
Week two: Reduce to every other day of burping as moisture levels stabilize.
Chlorophyll continues breaking down, smoothing the harsh edge.
Jars should hold 58-62% humidity.
Weeks three and four: Burp twice weekly.
The dramatic changes are over.
Terpenes become more pronounced, smoke gets smoother, and flavor emerges.
Keep the environment at 60-70 degrees in darkness.
Grove Bags with TerpLoc self-regulate humidity after the initial two-week active cure when moisture has equalized.

How to Know When a Bud is Done Curing
The cure is done when the smell has fully developed into a strain aroma, the texture passes the squeeze test with spring-back, the smoke burns clean to white ash, and your hygrometer consistently reads 58-62% after minimal burping.
Most reach this between two and four weeks.
Sample at two weeks, then three, then four to notice the progression.
Fixing Ammonia, Hay Smell, and Overdry Mistakes
Ammonia smell or fog means anaerobic bacteria from excess moisture above 65% RH.
Spread buds on screens immediately and check for white/gray fuzzy mold.
Mold usually means the batch is lost.
Permanent hay smell comes from too-fast initial drying (under 7 days or below 45% humidity).
Extended curing for 6-8 weeks improves smoke smoothness, but bright terpenes won't return.
Overdry recovery works when buds are below 55% humidity but haven't turned to dust.
Use a humidity pack briefly or a slightly damp paper towel in a separate container, checking every few hours.
Bring moisture back to 58%, don't soak.
Terpene loss is permanent, but you can achieve decent smoothness.
Why Does My Weed Smell Like Hay?
Hay smell develops when the initial drying phase happens too fast, preventing natural chlorophyll breakdown.
This usually means the drying room stayed below 45 % humidity or temperatures exceeded 75 degrees, pulling moisture out in under seven days.
Once that grass smell sets in during a rushed dry, extended curing may improve smoke quality, but rarely restores the full terpene complexity that should have been there.
Can You Fix Harsh Weed After Curing?
Extended curing can improve smoke smoothness by continuing chlorophyll breakdown even when initial drying was rushed, but terpenes lost to overdrying won't return.
If harshness comes from incomplete curing rather than overdrying, another four to six weeks in jars at proper humidity will help.
If harshness comes from a too-fast dry that stripped terpenes, the smoke will get smoother, but the flavor profile stays muted.
How Long to Cure for Good, Better, and Best Results
Cannabis becomes smokeable after 2-4 weeks of curing at 58-62% humidity, though 4-8 weeks delivers noticeably smoother smoke with richer flavor profiles.
The cure duration spectrum breaks into clear quality tiers.
Two to four weeks produces minimally smokeable flower with harshest edges gone.
Four to eight weeks is where quality jumps.
Chlorophyll completes breakdown, terpenes fully express, smoke becomes genuinely smooth.
Six months and beyond is connoisseur territory with subtler gains.
Cannabis loses 31% of terpenes after one week of drying and 55% after three months.
Proper technique preserves what rushed drying destroys.
Time investment justifies premium pricing.
Flower rushed through one-week processing can't compete with slowly dried and cured flower.
Is Weed More Potent After Curing?
Curing allows remaining moisture to evenly distribute throughout the bud while cannabinoids stabilize, though the primary increase in potency happens during drying when THCa becomes more concentrated as water weight decreases.
Proper curing preserves the cannabinoids that would degrade with rushed processing or poor storage, maintaining the potency that developed during growing and initial drying.
Evaluating Store-Bought Flower for Proper Curing
The same finish-line signals that tell you your cure is complete also help evaluate purchased cannabis quality.
A properly cured flower should release an immediate aroma when opened, not faint notes requiring hard sniffing.
Pick up a bud and gently squeeze.
Dry exterior with an interior that slowly springs back.
Crumbly means over-dried, damp/sticky means under-cured or poor storage.
The burn test works on any flower.
Clean cannabis burns evenly, leaving a light gray to white ash.
Black, oily ash indicates incomplete curing.
This white ash test is what Mood administers to every batch as proof of proper curing.
Lab reports showing 10-15% moisture content signal proper curing.
Too low means harsh smoke and terpene loss, too elevated creates mold risk.
Quality producers include this specification.
Mood's quality control catches curing issues before shipping.
Every batch undergoes burn testing and moisture verification.
Slightly dry flower gets re-cured to restore proper moisture.
The 90-day guarantee removes assessment burden.
Replacement or refund eliminates the risk of getting stuck with poorly processed flower.

Storing Cured Flower So Quality Lasts Months
Proper storage preserves all the work that went into achieving a quality cure, whether you finished the process yourself or purchased expertly cured flower.
Store at 58-62% humidity in airtight containers kept at 60-70 degrees in complete darkness.
Temperature stability matters more than hitting an exact number.
Fluctuations cause condensation and mold.
Light degrades THC into CBN.
After cure completes, humidity packs maintain ideal conditions.
Replace every 2-3 months.
The two-jar approach protects bulk stash.
Use a large jar for long-term storage, rarely opened.
Use a small working jar for 1-2 weeks of use.
Every opening introduces oxygen and moisture loss.
Quality benchmarks: At one month, no difference from day one.
At three months, 85-90% of original characteristics remain.
At six months, 70-80% with proper storage.
Mood's cannabis is slow-cured and sealed for maximum freshness in heat-sealed, light-proof pouches.
How Long Can Cured Weed Last?
Properly cured and stored cannabis maintains quality for three to six months at 85 to 90 % of its original characteristics, with up to two years possible under ideal conditions though terpene complexity gradually fades after the six-month mark.
Vacuum sealing removes oxygen and extends preservation beyond what standard jars can achieve, making it worthwhile for long-term storage of larger quantities.
Visual Signs and Strain Differences to Watch For
Small stems inside buds should snap cleanly when the cure is complete.
Pistils fade from vibrant colors to subdued brownish hues. Trichomes remain intact as a frosty coating.
Dense indica buds hide moisture and need extra vigilance during burping.
Airy sativa buds dry faster and risk becoming brittle.
Your Complete Decision Framework
Knowing when cannabis curing is complete comes down to checking multiple signals that converge on the same answer.
The smell has evolved from hay or grass to a rich, strain-specific aroma with no ammonia.
Texture passes the squeeze test with a dry exterior and springy interior, smoke burns clean to white ash, and jars hold 58-62% RH after minimal burping.
The 24-hour jar test gives exact readings and actions for every moisture level.
Managing weeks 1-4 with proper burping prevents mold and overdrying.
Fix problems early.
Spread ammonia-smelling buds immediately or gently rehydrate below 55% RH.
Extended curing 4-8 weeks delivers noticeable improvements over 2-4 week minimum.
Proper storage preserves quality for months.
