n this article, we’ll explore the science behind curing, how long it takes to cure weed, how to do it correctly, and how it affects the final smoking experience.
What Is Cannabis Curing and Why Is It Important?
Curing is the process of slowly removing excess moisture from harvested cannabis buds while preserving essential compounds like terpenes and cannabinoids. Unlike drying, which removes most surface moisture within a few days, curing allows for a more controlled degradation of plant matter, resulting in smoother smoke and enhanced flavors.
Why Is Curing Important?
A proper curing process significantly improves the quality, potency, and overall smoking experience of cannabis. Here’s why:
- Enhances Flavor and Aroma – Terpenes are responsible for the unique scent and taste of cannabis. A slow cure prevents terpene degradation, keeping the buds flavorful and aromatic.
- Reduces Harshness – Freshly harvested cannabis contains chlorophyll and other plant byproducts that can make the smoke harsh. Curing breaks down these compounds, resulting in a smoother inhale.
- Increases Potency – Cannabinoids, such as THC and CBD, continue to develop during curing. Proper storage conditions help optimize their effects and prevent premature degradation.
- Prevents Mold and Bacteria Growth – Slowly reducing moisture content ensures that buds don’t retain excessive humidity, which could lead to mold formation and spoil the harvest.
Without a proper cure, even the highest-quality cannabis can end up tasting grassy, feeling harsh on the throat, and lacking its full psychoactive potential.
How Long Does It Take to Cure Weed?
One of the most frequently asked questions among cannabis growers is: how long does it take to cure weed? The answer depends on several factors, including humidity, temperature, and storage methods, but a proper cure typically takes between 2 to 8 weeks.
General Timeline for Curing Cannabis
- Week 1–2: The initial stage where most moisture leaves the buds, and chlorophyll breakdown begins.
- Week 3–4: Terpenes and cannabinoids stabilize, enhancing flavor and potency.
- Week 5–8: The final phase, where buds reach peak smoothness, aroma, and effect. Some growers cure for even longer (3–6 months) for maximum quality.
By understanding how long does it take to cure weed, growers can fine-tune their process to ensure the best results.
Factors That Affect Curing Time
Several conditions can impact the duration of the curing process:
- Humidity Levels: The ideal relative humidity (RH) inside curing jars should be between 58%–62%. If humidity is too high, mold can develop; if it’s too low, buds may dry out too quickly and lose potency.
- Temperature: The best temperature for curing is 60–70°F (16–21°C). Higher temperatures can degrade cannabinoids, while lower temperatures slow down the process.
- Bud Density: Denser buds retain moisture longer and may require a slightly extended cure.
- Curing Method: Traditional glass jar curing takes longer but provides better results compared to faster methods like vacuum sealing.
While cannabis can be smoked after a short cure (2 weeks), waiting the full 4 to 8 weeks ensures a smoother, more potent, and flavorful final product.
Environmental factors can influence the curing process. Consult our Cannabis Grow Map to understand how regional climates impact cultivation.
The Science Behind the Curing Process
Curing cannabis isn’t just about drying—it’s a controlled chemical process that preserves cannabinoids, enhances terpenes, and improves overall quality. Understanding how long does it take to cure weed helps explain why rushing the cure can ruin a harvest and why longer curing times lead to better weed.
Breaking Down Chlorophyll for a Smoother Smoke
Freshly harvested cannabis contains high levels of chlorophyll, which gives buds a harsh, grassy taste. During curing:
- Chlorophyll molecules break down naturally, reducing the harshness of the smoke.
- Other plant byproducts (like sugars and starches) also degrade, preventing irritation when inhaled.
Terpene Preservation: Why Slow Curing Matters
Terpenes are the aromatic compounds responsible for flavor and aroma in cannabis. These compounds are delicate and degrade easily, especially when exposed to heat, light, and oxygen.
Fast drying destroys terpenes, leading to less flavorful buds.
A slow cure at the right humidity (58–62%) helps preserve terpenes, keeping the strain’s unique scent and taste intact.
By carefully managing how long does it take to cure weed, growers can protect these vital compounds and maximize the cannabis experience.
Cannabinoid Development: The Key to Potency
During curing, THC (tetrahydrocannabinol) continues to mature, which can slightly increase potency over time. If stored improperly:
- Too much oxygen leads to THC degrading into CBN (cannabinol), which has more sedative effects.
- Too little oxygen can cause mold or bacterial growth.
By maintaining ideal curing conditions, growers ensure that their cannabis remains potent, smooth, and aromatic for months—or even years.
Step-by-Step Guide to Curing Weed Properly
Curing cannabis correctly requires patience and the right conditions. Knowing how long does it take to cure weed is key to achieving the best results. Follow these steps to ensure maximum potency, flavor, and smoothness in your final product.
Step 1: Drying the Buds
Before curing, cannabis must be properly dried to remove most surface moisture.
- Hang buds upside down in a dark, well-ventilated room with temperatures around 60–70°F (16–21°C) and humidity at 50–60%.
- Drying takes 7–10 days—buds are ready when the small stems snap instead of bending.
Step 2: Storing in Airtight Jars
Once dried, buds should be placed in glass jars with airtight lids (mason jars work best).
- Fill jars about ¾ full, leaving space for air circulation.
- Store in a cool, dark place at 60–65% humidity.
Step 3: Burping the Jars (First Two Weeks)
For the first 14 days, open the jars once or twice a day for a few minutes to release built-up moisture and allow fresh air in.
- If buds feel too moist or stick together, leave the jar open longer.
- If they feel too dry, use humidity control packs (like Boveda 58–62%) to maintain moisture balance.
Step 4: Monitoring and Adjusting Humidity
- Ideal humidity inside jars should stay at 58–62%.
- Use a hygrometer inside jars to monitor humidity levels.
- If moisture levels are too high (above 65%), leave the lid open for a few hours.
Step 5: Finalizing the Cure
- By week 3–4, burping can be reduced to once every few days.
- By week 6–8, buds should be fully cured, smooth, and flavorful.
- For premium-quality cannabis, some growers extend curing for 3–6 months.
By controlling how long does it take to cure weed, you can ensure a premium-quality final product.
How Curing Affects the Effects of Weed
Curing doesn’t just improve the taste and smoothness of cannabis—it also directly impacts its potency, psychoactive effects, and overall experience. Understanding how long does it take to cure weed is essential to maximizing its full potential.
1. Improved Potency and Cannabinoid Stability
- During curing, THC continues to develop, slightly increasing potency over time.
- A proper cure also prevents THC degradation into CBN, which has more sedative effects.
- Buds that aren’t cured correctly can lose up to 15% of their THC content due to oxidation.
2. Enhanced Flavor and Aroma
- Freshly harvested cannabis can taste grassy or harsh due to leftover chlorophyll.
- Curing preserves delicate terpenes, allowing the strain’s unique flavors and aromas to fully develop.
- Strains with citrusy, fruity, or gassy profiles especially benefit from slow curing.
3. Smoother Smoke and Better Combustion
- Well-cured cannabis burns evenly and smoothly, while improperly cured buds may be harsh, cough-inducing, or difficult to keep lit.
- The breakdown of residual plant starches makes smoke less irritating to the throat and lungs.
4. Longer Shelf Life and Consistent Effects
- Properly cured and stored weed can retain potency and flavor for up to two years.
- Buds that aren’t cured correctly lose potency, dry out, or develop mold within weeks or months.

Common Mistakes When Curing Weed (And How to Avoid Them)
Even experienced growers can make mistakes when curing cannabis. Understanding how long does it take to cure weed and avoiding these common pitfalls ensures your buds retain maximum potency, flavor, and smoothness.
1. Drying Too Quickly or Too Slowly
Problem: Drying weed too fast (less than 5 days) locks in harsh chlorophyll, while drying too slowly (over 2 weeks) increases the risk of mold.
Solution: Maintain an ideal drying environment: 60–70°F (16–21°C) and 50–60% humidity. A slow, controlled dry over 7–10 days is ideal.
2. Storing Buds with Too Much Moisture
Problem: If buds are jarred while too wet, mold can develop.
Solution: Ensure small stems snap (not bend) before curing, and monitor jar humidity (should be 58–62%). If humidity exceeds 65%, leave jars open for a few hours.
3. Not “Burping” the Jars Enough
Problem: Skipping the burping process can cause moisture buildup, leading to mold or ammonia-like smells.
Solution: For the first 2 weeks, open jars once or twice daily for a few minutes to release excess moisture. After that, burp the jars once every few days.
4. Over-Drying the Buds Before Curing
Problem: Buds that are too dry before curing lose terpenes and potency, resulting in a harsh, weak product.
Solution: If buds feel crumbly or below 55% humidity, use humidity control packs (e.g., Boveda 58–62%) to restore balance.
5. Storing Weed in Plastic Bags Instead of Glass Jars
Problem: Plastic bags don’t regulate humidity, causing buds to dry out or become overly moist.
Solution: Always cure cannabis in airtight glass jars, which provide the best humidity control and terpene preservation.
6. Exposing Curing Buds to Light and Heat
Problem: Light and heat degrade THC, reducing potency over time.
Solution: Store curing jars in a cool, dark place (60–70°F/16–21°C) to prevent degradation.
By avoiding these mistakes, you can ensure a perfect cure every time, leading to stronger, smoother, and more flavorful cannabis.
