Different cannabis products (flower, edibles, concentrates, tinctures, and so on) have different storage requirements. If you simply purchased more cannabis at your dispensary then you plan to consume that day, follow the instructions on the packaging or those provided by your bud tender for storing excess product. In general, keep the product in its original packaging (assuming it’s airtight) and store it in a cool, dark place out of the reach of children and other critters.
If you need to store substantial amounts of flower for extended periods of time, follow these guidelines:
1. Store in a cool, dry place out of direct sunlight. Cool means between 77 and 86 degrees Fahrenheit. Dry means relative humidity of between 59 and 63 percent. You can use a thermometer to measure temperature and a hygrometer to measure humidity.
2. Don’t store in a refrigerator or freezer. In a refrigerator, temperature and humidity fluctuations make cannabis more susceptible to mold and mildew. In a freezer, the trichomes tend to become brittle and fall off when handled.
3. Store in glass, metal, or wood containers. Plastic bags and containers are susceptible to developing a static charge that attracts the trichomes. Plastic is okay for short-term storage.
4. Vacuum-seal your jars or other containers to remove excess air. Too much air can cause oxidation, which degrades the quality of the cannabis.
