What Are Cannabis Curing Containers?
The cannabis curing containers is post process of cannabis cultivation step in the post-harvest process of cannabis cultivation. It involves storing dried cannabis buds in a controlled environment to gradually improve their flavor, aroma, and potency. When cannabis is first harvested and dried, it still contains chlorophyll and other undesirable compounds that can affect its taste and smoothness. Through curing, these compounds break down, while terpenes and cannabinoids develop, resulting in a better overall experience.
In this stage, the right container is essential to ensure the cannabis buds don’t lose their valuable moisture too quickly or, on the other hand, retain too much moisture, which can cause mold. A well-chosen curing container allows growers to extend the shelf life of their buds while preserving their quality. This makes the curing process not just a preservation method but an enhancement process that brings out the best in cannabis.
By creating an environment with optimal humidity and minimal air exposure, curing containers allow the cannabis buds to continue maturing even after drying. This slow process of moisture redistribution within the buds stabilizes the cannabinoids and terpenes, which can ultimately lead to smoother smoke, richer flavors, and more pronounced effects.
Key Features of Cannabis Curing Containers
When selecting a container for curing cannabis, understanding its features is critical for success. One of the most important elements is ensuring that the container is airtight. This helps prevent any unwanted airflow, which can accelerate the drying process and lead to overly brittle buds. An airtight seal also helps maintain the delicate balance between moisture retention and mold prevention, both of which are critical for effective curing.
Odor control is another key feature, particularly for growers who are looking to keep their curing process discreet. Cannabis has a strong aroma that intensifies during curing, so a good container should be able to lock in odors. This not only keeps the curing environment consistent but also prevents the smell from escaping into the surrounding area.
The material of the container is also important. Glass, for example, is a non-reactive material that doesn’t interact with the terpenes or cannabinoids. On the other hand, plastic containers may be more affordable but could potentially affect the quality of the cannabis by releasing chemicals or altering the flavor. Understanding these features will help growers make an informed decision about the best containers for their curing needs.
Best Types of Containers for Cannabis Curing
Glass Mason Jars
Glass mason jars have long been a favorite among cannabis growers for curing. Their transparent, airtight design provides the perfect environment for slowly curing buds without exposing them to excessive light or air. They are widely available and come in a range of sizes, making them a versatile choice for both small-scale and large-scale growers.
One of the significant advantages of glass mason jars is that they do not interact with the contents inside. The non-reactive glass preserves the terpenes and cannabinoids, ensuring that the flavor and potency remain unchanged. However, due to their transparency, it is essential to store glass jars in a dark place, such as a cupboard, to prevent light from degrading the cannabinoids over time.
Additionally, glass mason jars are reusable and easy to clean, making them a long-lasting option for those who regularly grow and cure cannabis. Their ability to be sealed tightly means that they effectively control humidity levels within the jar, reducing the need for frequent burping during the curing process. While they may be fragile, careful handling makes them a reliable option for achieving high-quality cured cannabis.

Plastic Containers
Plastic containers may seem like an inexpensive alternative to glass, but their shortcomings make them less suitable for curing cannabis in the long term. Plastic is a porous material that can absorb smells and flavors over time, which may interfere with the cannabis’s natural aroma and taste. Furthermore, some plastics contain chemicals that can leach into the cannabis, potentially affecting its safety and quality.
However, plastic containers do have their place in the curing process, particularly for temporary storage. They are lightweight and easy to transport, making them useful for growers who need a quick, portable solution. If using plastic containers, it’s essential to choose high-quality, food-grade plastic to minimize the risks of contamination or flavor alteration. For short-term use, plastic containers can serve as a stopgap solution until better options are available.
To mitigate the potential downsides of plastic, growers may line the inside of the container with parchment paper or use specialized cannabis storage bags that are designed to protect the buds from the adverse effects of plastic. However, for the best results, plastic containers should be avoided for long-term curing whenever possible.
Stainless Steel Containers
Stainless steel containers represent a modern, highly durable option for cannabis curing. These containers offer the advantage of being virtually indestructible, meaning they can be reused over and over again without breaking down or losing their effectiveness. Stainless steel is also non-reactive, much like glass, ensuring that the cannabis inside is protected from external contaminants.
Many stainless steel containers feature vacuum-sealed lids, which provide an even more controlled curing environment. By reducing the air exposure inside the container, vacuum-sealed lids slow down the degradation of cannabinoids and terpenes, extending the shelf life of the cured cannabis. Stainless steel containers are ideal for growers dealing with larger quantities of cannabis, as they often come in larger sizes than traditional glass jars.
Though more expensive upfront, the durability and effectiveness of stainless steel containers make them a worthwhile investment for serious cannabis growers. Additionally, the ability to create a vacuum seal reduces the need for frequent burping, allowing for a more hands-off approach to curing. Their robust construction and versatility make stainless steel containers a top-tier choice for cannabis curing.
Vacuum-Sealed Containers
Vacuum-sealed containers provide an advanced option for curing cannabis, particularly for growers who want to minimize oxidation and preserve the potency of their buds for an extended period. These containers work by removing air from the inside, which slows down the degradation process and helps maintain a stable humidity level within the container. The vacuum seal also prevents mold from forming by keeping moisture levels under control.
For those looking to achieve the best possible results from their curing process, vacuum-sealed containers are an excellent choice. They are particularly effective when used in combination with humidity packs, which help regulate moisture without the need for constant monitoring. However, the initial investment in vacuum-sealed containers and equipment can be higher, making this option more suited to experienced growers who are committed to maximizing the quality of their cannabis.
While vacuum-sealed containers offer many benefits, they require careful management. Growers must ensure that the vacuum-sealing process is done correctly to avoid over-compressing the buds, which could negatively affect their structure. When used properly, these containers allow for efficient curing with minimal risk of oxidation or mold growth.
Tips for Proper Cannabis Curing
Start with Dry Cannabis
Achieving optimal results from the curing process begins with properly dried cannabis. After harvesting, cannabis should be dried until the outer surface of the buds is no longer moist to the touch, but the stems are still slightly flexible. Over-drying the cannabis can result in harsh, brittle buds, while under-drying can lead to mold growth during the curing phase.
It’s important to strike the right balance by drying the cannabis slowly in a controlled environment. Once the buds have reached the ideal level of dryness, they can be transferred to curing containers to begin the curing process. Properly dried cannabis will continue to release small amounts of moisture during curing, which helps refine the flavor and potency over time.
By ensuring that the cannabis is sufficiently dry before curing, growers can reduce the risk of mold and other issues that may compromise the quality of their harvest. Drying is the first step toward achieving high-quality cured cannabis, and careful attention to this stage will pay off in the final product.
Burping the Jars
The process of burping the jars is an essential step in cannabis curing. Burping involves opening the containers to release built-up gases and allow fresh air to circulate inside. This helps regulate humidity levels and prevents the buds from becoming too moist, which could lead to mold growth. During the first week of curing, it’s recommended to burp the jars at least once or twice a day for a few minutes.
As the curing process progresses and the cannabis stabilizes, the frequency of burping can be reduced to once every few days. By the third or fourth week, burping once a week is often sufficient. However, growers should continue to monitor the buds for any signs of moisture imbalance, as some strains may require more frequent burping depending on their density and moisture content.
Burping allows growers to maintain control over the curing environment without disrupting the process too much. By opening the jars at regular intervals, growers can ensure that the cannabis cures evenly and that the buds develop their full aroma and flavor.
Use Humidity Packs
Humidity packs are a useful tool for ensuring consistent moisture levels during the curing process. These packs are designed to maintain an optimal humidity range, typically around 58-62%, which is ideal for curing cannabis. By placing a humidity pack inside the container, growers can reduce the need for constant monitoring and burping, as the pack will regulate the environment automatically.
Brands like Boveda and Integra Boost offer humidity packs that are specifically designed for curing cannabis. These packs work by absorbing excess moisture when humidity levels are too high and releasing moisture when levels are too low. This helps maintain a stable curing environment, which is essential for preserving the quality of the buds.
In addition to reducing the need for frequent burping, humidity packs can also help prevent the buds from becoming too dry, which can negatively affect their potency and flavor. For growers looking for a low-maintenance way to cure cannabis, humidity packs are an excellent addition to the curing process.
Store in a Cool, Dark Place
Light and heat are two of the biggest enemies of cannabis curing. Exposure to light can degrade cannabinoids like THC and CBD, reducing the potency of the buds over time. Heat can also accelerate the breakdown of terpenes, which are responsible for the aroma and flavor of the cannabis. To avoid these issues, it’s essential to store curing containers in a cool, dark place, away from direct sunlight and high temperatures.
A closet, cupboard, or basement are all good options for storing curing containers. The ideal temperature range for curing cannabis is between 60-70°F (15-21°C). Storing the containers at this temperature will help slow down the degradation process and preserve the quality of the buds for a longer period.
By taking the time to store cannabis properly during curing, growers can protect their harvest from the negative effects of light and heat. This ensures that the buds remain potent, flavorful, and aromatic, even after several weeks or months of curing.
Monitor Humidity and Temperature
Regularly monitoring the humidity and temperature inside curing containers is a crucial part of the process. A small hygrometer can be placed inside the container to measure humidity levels, allowing growers to make adjustments if necessary. If the humidity rises above 70%, it’s essential to burp the jars more frequently to release excess moisture and prevent mold from forming.
Temperature should also be monitored, as higher temperatures can lead to the evaporation of valuable terpenes and cannabinoids. Keeping the curing containers in a stable environment with consistent temperature and humidity levels will help ensure that the cannabis cures evenly and develops its full potential.
By keeping a close eye on humidity and temperature, growers can catch any issues early on and make adjustments to ensure a successful curing process. This attention to detail is what separates good cannabis from great cannabis.
How Long Should Cannabis Cure?
Curing is a process that requires patience. While some growers may be eager to start consuming their cannabis after just a couple of weeks, those who allow their buds to cure for a longer period will be rewarded with superior flavor, potency, and smoothness. The length of time required for curing depends on the strain, personal preference, and the environment in which the cannabis is stored.
2-3 Weeks: This is the minimum curing time recommended for cannabis. After two to three weeks, the buds will have lost their grassy or chlorophyll taste, and the terpenes will start to become more pronounced. However, the buds may still be slightly harsh on the throat, and the full flavor potential may not yet be realized.
4-6 Weeks: For most strains, curing for four to six weeks will produce a more balanced and refined product. By this point, the terpenes and cannabinoids will have fully developed, resulting in a smoother, more flavorful smoking experience. The buds will also be more potent, with a more pronounced aroma.
8 Weeks or More: Some growers prefer to cure their cannabis for two months or even longer. Extended curing times allow the buds to reach their peak in terms of flavor, aroma, and potency. The longer the cure, the smoother the smoke and the richer the terpene profile. While curing for more than eight weeks may not be necessary for all strains, it can produce exceptional results for those who are willing to wait.

How to Tell When Cannabis is Fully Cured
Fully cured cannabis should have a pleasant aroma that reflects the strain’s terpene profile. The buds should feel firm but not dry, with a slight stickiness when handled. When squeezed, properly cured cannabis should compress slightly before returning to its original shape. If the buds crumble easily or feel too dry, they may have over-dried during the curing process.
In addition to texture and aroma, the smoke quality of fully cured cannabis will be smooth and flavorful, with minimal harshness on the throat. The effects of the cannabis should also be more pronounced, with a well-rounded high that reflects the full potential of the strain.
FAQs About Cannabis Curing Containers
Can I use Tupperware for curing cannabis?
Tupperware or other plastic containers are not recommended for long-term curing because they are not fully airtight, and plastic is a porous material that can absorb odors and flavors. Over time, the plastic may impart unwanted chemicals or tastes to the cannabis, affecting its quality. In some cases, plastic containers may also trap excess moisture, leading to the growth of mold or mildew on the buds.
However, if you’re in a pinch, plastic containers can be used for short-term storage during the drying phase or if you need a temporary solution for transporting buds. Be sure to line the container with parchment paper to minimize contact between the plastic and the cannabis. For the best results, it’s recommended to transfer the cannabis to an airtight, non-reactive container, such as a glass jar, once it’s time to begin the curing process.
Is it necessary to use humidity control packs?
Humidity control packs are not strictly required, but they can greatly improve the curing process by helping to maintain a consistent humidity level. Curing cannabis without humidity packs requires frequent monitoring and burping to ensure that moisture levels remain stable. If the humidity level rises too high, there is a risk of mold; if it drops too low, the buds may dry out and lose potency.
Using humidity packs, such as those from Boveda or Integra Boost, simplifies the process and allows for more hands-off curing. These packs automatically adjust the moisture levels inside the container, keeping the humidity within the optimal range of 58-62%. This reduces the need for frequent burping and helps ensure a smooth, even cure, preserving the buds’ flavor, aroma, and potency.
How often should I burp my curing containers?
During the first week of curing, it’s recommended to burp your containers once or twice a day to release any built-up gases and excess moisture. Each burping session should last a few minutes, allowing fresh air to circulate inside the container. After the first week, you can reduce burping to once every few days. By the second or third week, burping once a week is usually sufficient.
The frequency of burping depends on the strain and moisture content of your buds. Some strains, especially those with dense buds, may require more frequent burping to prevent moisture buildup. Always monitor the humidity levels inside the container to ensure they remain within the ideal range. If you notice excessive moisture, increase the frequency of burping to avoid the risk of mold.
Can I cure cannabis in the refrigerator?
It is not recommended to cure cannabis in the refrigerator. The cold temperatures and fluctuating humidity levels inside a refrigerator can negatively affect the curing process. Refrigerators are typically too cold for proper curing, which can slow down the breakdown of chlorophyll and other compounds. Additionally, the varying humidity levels in a fridge can cause the buds to dry out too quickly or become too moist, both of which can reduce the quality of the cured cannabis.
For the best results, cannabis should be cured in a stable environment with a consistent temperature of 60-70°F (15-21°C) and a humidity level of 55-65%. A cool, dark, and dry space such as a cupboard or closet is ideal for curing. This environment allows the buds to develop their full flavor and potency without the risk of degradation from cold temperatures or fluctuating humidity.
What should I do if my cannabis is too dry during curing?
If your cannabis becomes too dry during the curing process, there are a few steps you can take to rehydrate it. One of the simplest methods is to add a humidity control pack to the container. These packs will help restore the moisture balance within the container and prevent the buds from becoming overly brittle.
Another method is to introduce a small piece of citrus peel, a damp paper towel, or a fresh cannabis leaf into the container for a short period. These items will release moisture into the environment, allowing the buds to reabsorb some of the lost moisture. However, this method requires careful monitoring to ensure that the container does not become too humid, which could lead to mold growth.
If using organic items like citrus peel or a damp towel, be sure to remove them after a few hours to prevent over-humidifying the container. Once the desired moisture level is restored, the buds can continue curing as normal.
