In the image, we see a person wearing blue gloves holding a trimmed cannabis bud. The person is wearing a black apron or shirt with the “BudTrainer” logo in the background, making the context related to growing or processing cannabis. The bud appears well-trimmed, with visible trichomes and a reddish tint in the hairs, indicating maturity.

We do not endorse the production of illegal substances and it is your duty to ensure that you are complying with the law. The words "hemp", "cannabis", "weed", and "marijuana" are used interchangeably to refer to the same plant (legal hemp with less than 0.3% THC) for the purposes of this lesson.


Perfecting Your Harvest with Trimming & Curing

Proper trimming ensures that your buds are clean, potent, and ready to enjoy, while careful curing locks in flavor and potency. Rushing through this process can lead to harsh smoke and degraded cannabinoids, but when done right, you’ll be rewarded with smooth, flavorful, and potent cannabis that showcases your hard work. Let’s go through the steps to make sure your harvest is finished with perfection.

Tools & Materials

  1. Plastic tray for trim
  2. Disposable gloves
  3. Trimming scissors
  4. Glass jars
  5. 2-way humidity packs

How to Cure Cannabis

After your buds go through the drying process and your stems are snapping, it doesn’t mean that your flowers are fully dry. It only means that their surface is dry, but the center is still moist. In fact, the core of your bud will always be more moist during the drying process because moisture flows from the inside out. 

This is not ideal because it means your weed has different levels of moisture content across its profile - the outside being dry and crunchy (at the ambient 55% RH) and the inside still being soft and wet (at more than 55% RH).

This image depicts a stylized illustration of a cannabis bud with several arrows pointing outward, likely indicating airflow or water distribution around the plant. It emphasizes the importance of balanced airflow or watering techniques, which are essential to ensuring healthy growth and preventing issues like mold. The “BudTrainer” logo is visible at the bottom right, suggesting this is part of an educational or instructional graphic.

Using Mason Jars

In order to make sure the internal moisture comes back out, you need to cure your buds. Curing involves placing your recently trimmed flowers into airtight containers (we recommend using mason jars that sell everywhere) until the moisture from the inside of the bud has come out and evened out with the dryness from the outside.

This image shows an overhead view of a glass jar filled with dried cannabis buds. The buds appear dense with a light green color and have orange pistils scattered throughout, covered in a frosty layer of trichomes. The “BudTrainer” logo is visible in the lower right corner of the image, indicating it is part of branding or product content for BudTrainer. The overall composition emphasizes the quality and texture of the buds stored in the jar.

2-Way Humidity Packs

During this process water will be moving from the center of the flowers to the outside, and from the outside into the airtight container. Eventually the relative humidity inside the container will start rising, which is why it is recommended to use a 2-way humidity control pack. These humidity packs have a fixed humidity rating and they either bring the moisture level up or down inside of your container. Here at BudTrainer® we recommend curing cannabis at a relative humidity of 55% to 62%.

"Burping" Your Jars

Since there is still a significant amount of moisture to come out of your buds, it is essential that you open your containers (AKA burping) at least twice a day for a minimum of 5 minutes. This will allow the high-humidity air from inside the jar to come out and be replaced by drier air from the outside. To help you know the exact humidity inside your jar, you can buy mini hygrometers on Amazon like the one in the photo below.

This image features a glass jar filled with cannabis buds, alongside a digital hygrometer placed inside the jar to monitor humidity. The hygrometer displays a reading of 56% relative humidity (RH) and 68.4°F, which suggests an optimal environment for curing and storing cannabis. A Boveda humidity control packet is also visible, used to maintain the ideal humidity levels inside the jar. The lid of the jar is open and placed next to it, and the BudTrainer logo is displayed in the lower right corner. The backg

When Is Curing Finished?

Curing usually takes 2 to 4 weeks, and this amount of time depends on how much you dried your plants before. Cannabis can be cured for only 1 week and be ready for consumption, or it can cure for 3 weeks and still need longer to go. In our experience, 2 weeks is the ideal time to cure before consuming.

Since every strain is different, the easiest way to tell is by consuming a small nug after each week, until you are happiest with the experience. We find that “putting it to the test” is the best way to tell when your plants are really ready to go.

P.S. Don't forget to label your jars!

The bud is frosty with visible trichomes and orange pistils, showcasing its resinous, crystal-covered surface. The lighting accentuates the texture and details of the bud, with the green leaves and orange hairs standing out vividly. The BudTrainer logo is subtly visible in the lower right corner.
