5.5 Post-Harvest Curing and Storage for Optimal Potency

Cartier April 11, 2023

Proper curing and storage of your cannabis harvest play a vital role in preserving its potency, flavor, and overall quality. Inadequate curing and storage can lead to a decline in cannabinoid and terpene levels, negatively impacting the final product. This section will discuss the best practices for curing and storing cannabis harvest to ensure optimal potency and quality.

  1. Curing process:
    • Initial drying: After trimming, hang the cannabis branches or place individual buds on drying racks in a dark, well-ventilated room with a temperature of 60-70°F (15-21°C) and humidity levels between 45-55%. This initial drying process typically takes 5-15 days, depending on the specific conditions.
    • Curing in containers: Once the buds are dry to the touch and smaller stems snap when bent, transfer the buds to airtight containers, such as glass jars. Fill the jars about ¾ full, leaving enough room for air circulation. Seal the jars and store them in a cool, dark place.
    • Burping the jars: During the first week of curing, open the jars daily for 15-30 minutes to release excess moisture and replenish oxygen. This process, known as “burping,” helps prevent mold growth and ensures even curing. After the first week, burp the jars once every 2-3 days for 2-3 weeks.
    • Optimal curing duration: Depending on personal preference, the process can last 2-4 weeks or even longer. Generally, a longer curing period results in smoother, more flavorful smoke. However, be mindful that excessively long curing times may result in a decline in THC levels.
  2. Storage for optimal potency:
    • Light protection: Store your cured cannabis in a dark place, as exposure to light can degrade cannabinoids and terpenes. Opaque containers or a light-proof storage box can provide additional protection.
    • Temperature control: Maintain a consistent temperature between 60-70°F (15-21°C) during storage. Fluctuations in temperature can affect the potency and quality of your cannabis.
    • Humidity control: Keep the relative humidity within the storage area between 55-62% to prevent mold growth and preserve the cannabis’s freshness. Consider using humidity packs designed for cannabis storage to maintain optimal humidity levels.
    • Airtight containers: Use airtight containers to protect your cannabis from oxygen exposure, which can degrade cannabinoids and terpenes over time.

In conclusion, proper post-harvest curing and storage practices are essential for preserving the potency and quality of your cannabis harvest. By following the steps outlined above, you can ensure that your hard-earned yields maintain their optimal characteristics, providing a satisfying and enjoyable experience for the end user.
