How to Cure Cannabis: The Step-by-Step Guide

Learning how to cure cannabis effectively is important for any cultivator. Not only does the drying and curing process help to remove excess moisture from your harvest (which improves shelf life), but it can enhance product quality, improving the flavor and potency of the cultivar. 

Creating the ideal curing strategy can be an excellent way to scale your operations, increase your profits, and enrich the customer experience. However, there are several essential steps to follow to ensure you get the right results. The ideal outcome requires growers to create the perfect drying conditions, monitor factors like airflow, temperature, and humidity, and store dry buds correctly. 

Today, we’ll look at all of the key steps involved in the curing process and provide useful tips on how you can ensure you’re getting the most from every plant. 

How to Cure Cannabis: Step by Step

Discovering how to cure cannabis effectively can help to optimize the lifespan, potency, flavor, and aroma of the finished product. When given the proper care and attention, your buds can reach their full potential—and last in storage for months at a time—without diminished taste or potency. 

There are several steps involved in the process of curing cannabis, during which the molecular makeup of your flowers will continue to evolve. Some THC will convert to CBN, while certain terpenes will increase in potency. While the exact process you follow may vary depending on your chosen cultivar, you will need a selection of crucial resources to help you through the process, including:

  • Effective trimmers, buckers, and harvesting tools 
  • A dark and controlled environment where you can store your cannabis buds
  • Air-tight containers to eliminate contamination
  • Drying resources for removing excess moisture
  • Tools for testing the potency and quality of your product

Here are the key steps you’ll need to follow. 

Step 1: The Harvest

The first step in curing cannabis is harvesting your flower correctly. You’ll need to ensure you’ve trimmed the plant well, removing excess stems, leaves, and unnecessary plant material. Specialized trimming machines ensure you can preserve the quality of the cannabis buds without adding any extra plant material to your finished product. 

Additionally, an effective harvesting process will ensure you can separate the leftover biomass from your buds, so you can use it for other processes, such as composting, and the creation of oils and tinctures. 

Step 2: Preparing Buds for Curing 

Once you’ve harvested your plants, the next stage is preparing them for the curing process. The most important step is drying the buds, removing excess chlorophyll and moisture, so the terpenes and cannabinoids can flourish. The length of the drying process will vary depending on the cultivar chosen, and your trimming method. 

In some cases, the process can be shorter when utilizing wet trimming methods because most of the excess plant material can be removed, leaving less to dry. When dry trimming, you will typically hang harvested plants upside down to prevent buds from getting flattened during the drying process. With wet trimming, it’s common to use a specialist drying rack. In both instances, you’ll need a dedicated drying room. 

The best drying room will be dark to eliminate the impact of excess heat and sunlight. Sunlight UV rays can degrade the cannabis plant’s quality. 

When drying cannabis, you’ll need to ensure the temperature of the space is around 60-70°F, with a relative humidity level of no more than 65%. A hygrometer will give you an easy way to monitor these numbers and ensure you preserve the right conditions. 

Since air circulation is critical, it’s worth investing in a fan or air conditioning unit to help maintain the desired atmosphere. Drying cannabis buds by hanging them is a simple and easy method, but it may require more space than you have available. Larger plant branches are hung to dry rather than first separating individual buds through bucking. If you’re wet trimming—meaning you remove the excess plant material from the buds before drying—you’ll need a flat rack made of mesh to ensure optimal airflow around the buds as they dry.

Step 3: The Curing Process

Once the flower has been dried, it’s time to start curing it to increase its potency and improve its flavor and aroma. An airtight container is crucial to the curing process, as it will prevent excess air and contaminants from influencing product quality. Avoid using plastic bags or other products that aren’t impervious to oxygen. Glass jars are a great option for storage.

For the best curing results, pack buds loosely in the glass jar and seal each one completely before placing them in a cool, dark place. You’ll need to monitor them daily for signs of mold as the buds will continue to dry and will need fresh air in the jars. 

Pay attention to the humidity inside of the jar, ensuring it doesn’t go above 65%. If you need more moisture, add a humidity pack. Alternatively, if humidity levels are too high, leaving the lid off for a few hours can help excess moisture evaporate. 

The curing process will naturally begin after you’ve placed your buds in storage. During this stage, the buds continue to lose moisture as they dry further and cure. Many of the terpenes that give your product its unique flavor and aroma will start to flourish. 

A slow dry and cure will improve the flavor and aroma of your buds, preventing crucial compounds from breaking down. In general, after about 2 to 4 weeks in your airtight containers, your product should be cured enough to deliver a high-quality, flavorful, and aromatic experience. While some cultivars benefit from months of curing, others take less time overall. 

Step 4: Monitoring

While curing is a relatively organic process, it still requires work from the grower. A big part of knowing how to cure cannabis effectively is understanding how to monitor and preserve temperature, airflow, and humidity. When curing your product in airtight containers, check the buds a day or so after the process begins, paying attention to the humidity levels. During the first week, the lids on your jars should generally be removed once or twice a day to allow the buds to breathe. This is known as “burping” the product, and it allows excess moisture to escape. 

Following the first week, you can continue burping the product every few days, continuing through to the fourth week of the curing process. Keep monitoring the humidity levels with a hygrometer. If your jars have a humidity level higher than 65%, you may need to remove the lids for a short time so the buds can dry out again before resealing them. Other signs that your buds are too wet are if they take on an unusual smell of ammonia or mold begins to form. Once again, you’ll need to remove the lids on the jars to ensure the flowers can dry out. 

Keep in mind if you’re curing large quantities of your flower in a single curing room, you will need to pay careful attention to each batch. Check humidity levels, temperature, and airflow regularly for the first few weeks, and make sure the lights are turned off when you leave the room. 

Step 5: Testing Cured Cannabis Quality

The final step is testing the quality of your product. Accurate testing is essential for several reasons. First, it ensures the dried cannabis is safe for consumption by allowing you to check for any contaminants, such as mold or mildew. Testing also allows you to verify the potency and quality of the product, from its aroma and flavor to its overall appearance. 

There are various methods growers can use to check the quality of their cured product. For larger industrial growers, lab testing is a standard option. This involves sending a sample of the product to a laboratory for analysis. The lab can check for potency and contaminants, and other quality factors. Another option is to examine the smell and appearance of the buds.

A good product should have a vibrant color and a strong aroma. Some growers may also smoke or vaporize some of the product to test flavor and potency. When testing your cured product, look for:

  • Potency: Examine the CBD and THC levels to ensure they’re in the desired range
  • Aroma and flavor: Check for a strong and pleasant aroma and flavor
  • Appearance: The flower should have a vibrant color, free from discoloration
  • Contaminants: Pay attention to any signs of mold or other contaminants

Step 6: Storage

When properly stored, cured cannabis can maintain its flavor and potency for up to two years. Excessive heat and sunlight can cause cured buds to degrade, losing cannabinoids and terpenes.

The ideal storage conditions rely on three crucial factors—temperature, humidity, and light.

Lower temperatures help prevent the degradation of THC and also help to keep products dry. In addition, keeping humidity levels between 55-65% prevents mold and mildew and maintains aroma and flavor. Also, UV rays will naturally break cannabis over time, so keep your buds away from strong or direct light as much as possible.
