Proper storage is essential to maintain the potency, flavor, and freshness of your cannabis. Exposure to environmental factors like light, air, and moisture can degrade cannabinoids and terpenes over time. This guide outlines best practices for keeping your products in optimal condition.
Key Factors Affecting QualityThe following factors can compromise the quality and longevity of your cannabis:
- Light: UV rays break down cannabinoids, most notably converting THC into CBN, which is less psychoactive.
- Air/Oxygen: Overexposure to oxygen speeds up the degradation of cannabinoids and terpenes.
- Temperature: High temperatures can dry out cannabis and degrade cannabinoids and terpenes. It also increases the risk of mold growth in high-humidity environments.
- Moisture/Humidity: Too much humidity promotes mold and mildew growth. Too little humidity causes the product to dry out and become harsh.
The best storage solutions protect cannabis from the key factors listed above.
ContainersAirtight, glass containers are the preferred method for long-term storage.
- Glass Jars: These are non-porous and create an excellent seal, preventing air exposure and preserving flavor.
- Opaque/Tinted Containers: Light degrades cannabis. Use opaque containers or store clear glass containers inside a dark cabinet.
- Avoid Plastic Bags/Containers: Plastic can create static electricity that attracts and strips off trichomes (where cannabinoids and terpenes are concentrated). Plastic also contains chemicals that can leach into the cannabis, altering its flavor.
Store your cannabis in a cool, dark, and dry place.
Factor | Optimal Conditions | Why It Matters |
|---|---|---|
Temperature | Below 70°F (21°C) | Prevents cannabinoid degradation and avoids drying out the product |
Humidity | 59% to 63% RH (Relative Humidity) | The "sweet spot" to prevent mold while retaining moisture and flavor |
Light | Absence of light (dark area) | UV exposure degrades THC into CBN |
For products you plan to keep for longer than a few weeks, consider these additional steps.
- Use Humidity Packs: Two-way humidity control packets (e.g., those found in the cigar industry) are highly recommended. They actively maintain the optimal 62% humidity level within the container.
- Avoid Freezing: Freezing can make trichomes brittle and easily break off, reducing potency. If you choose to freeze, ensure the product is vacuum-sealed and thaw very slowly.
- Keep Away from Appliances: Avoid storing cannabis near heat sources or appliances that fluctuate in temperature (e.g., ovens, refrigerators, electronics).
