Why Is Post-Harvest Handling Important for Cannabis?Updated 6 months ago

Post-harvest handling is crucial to preserving the quality, potency, and overall value of your cannabis. Once the plants have been harvested, how you handle them can significantly impact their cannabinoid content, terpene profile, and final appearance. Proper post-harvest handling involves careful drying, curing, and storage processes, all of which are essential for ensuring that your cannabis reaches its full potential.

How Does Proper Drying Affect the Quality of Cannabis?

Drying is the first and one of the most important steps in post-harvest handling. Proper drying helps to preserve the potency, flavor, and aroma of your cannabis by slowly reducing the moisture content in the buds without degrading the cannabinoids and terpenes. If cannabis is dried too quickly, it can lead to harsh smoke and diminished flavor because the chlorophyll and other plant compounds don’t have enough time to break down. On the other hand, drying too slowly or in an environment with too much humidity can lead to mold growth, which can ruin the entire batch. To dry cannabis properly, hang the plants upside down in a dark, well-ventilated room with a temperature of around 60-70°F (15-21°C) and humidity levels between 50-60%. This process typically takes 7-14 days, depending on the size and density of the buds. During drying, monitor the environment closely to maintain optimal conditions and prevent any issues that could affect the final quality of your cannabis.

Why Is Curing Cannabis Important After Drying?

Curing is the process that follows drying and is critical for enhancing the potency, flavor, and smoothness of your cannabis. While drying removes the bulk of the moisture from the buds, curing allows the remaining moisture within the buds to redistribute and evaporate slowly. This gradual process helps to further break down chlorophyll, reduce harshness, and develop a more complex terpene profile. Properly cured cannabis not only tastes better but also has a longer shelf life, as the curing process helps to stabilize the cannabinoids and terpenes. To cure cannabis, place the dried buds in airtight glass jars, filling them about three-quarters full to allow for some air circulation. Store the jars in a cool, dark place and open them (a process known as "burping") daily for the first week to release excess moisture and replenish the air inside. After the first week, you can reduce burping to once every few days for the next 2-3 weeks. Curing typically takes at least two weeks, but many growers prefer to cure their cannabis for a month or longer to achieve the best results.

How Does Proper Storage Protect Cannabis Quality?

Even after drying and curing, how you store your cannabis can have a significant impact on its long-term quality. Proper storage protects the buds from light, air, and moisture, all of which can degrade cannabinoids and terpenes over time. To maintain the potency and flavor of your cannabis, store it in airtight glass jars in a cool, dark place with stable humidity levels. Excessive exposure to light can degrade THC into CBN, which can result in a less potent and more sedative product. Similarly, exposure to air can cause the buds to dry out and lose their terpene content, leading to a loss of flavor and aroma. Humidity is another critical factor; if the environment is too humid, mold can develop, but if it’s too dry, the buds can become brittle and harsh. Using humidity packs designed for cannabis storage can help maintain the ideal humidity level inside your storage jars, typically around 55-62%.

How Can Mishandling Cannabis Post-Harvest Impact Potency?

Mishandling cannabis after harvest can lead to a significant loss of potency and overall quality. Rough handling, improper drying, or curing techniques, and poor storage conditions can all contribute to the degradation of cannabinoids and terpenes. For example, if the buds are handled too roughly during trimming or packaging, the trichomes can be damaged or knocked off, leading to a loss of potency. Similarly, improper drying and curing can result in the loss of valuable terpenes, leading to a less flavorful and aromatic product. Over-drying can cause the cannabinoids to break down more quickly, reducing the overall effectiveness of the cannabis. Additionally, storing cannabis in an environment that’s too warm or exposed to light can accelerate the degradation of THC, reducing the potency and altering the intended effects of the product.

How Can You Ensure the Best Post-Harvest Results?

To ensure the best results from your post-harvest process, it’s important to be meticulous at every step. Start with a clean and well-organized workspace to minimize the risk of contamination. Invest in quality tools for trimming and curing, such as sharp scissors, glass jars, and humidity packs, to ensure your cannabis is handled properly. Pay close attention to the environmental conditions during drying and curing, and make adjustments as needed to maintain optimal temperature and humidity levels. Finally, be patient—rushing the post-harvest process can lead to inferior results, so take the time to dry, cure, and store your cannabis correctly. By following these guidelines, you’ll be able to preserve the full potency, flavor, and aroma of your cannabis, ensuring a high-quality final product that reflects the care and effort you’ve put into growing it.
