Why Proper Storage Matters
Improperly stored cannabis loses potency, flavor, and can even develop mold. Whether you buy an eighth or an ounce, proper storage ensures your cannabis stays fresh and effective for months.
The Enemies of Fresh Cannabis
Light UV light breaks down cannabinoids and terpenes faster than any other factor. A study from the University of London found that light was the single greatest factor in cannabinoid degradation.
Temperature Heat accelerates the degradation of THC into CBN, a less psychoactive cannabinoid. Ideal storage temperature is 60-70°F (15-21°C). Never store cannabis near heat sources.
Humidity Too much humidity promotes mold growth. Too little humidity dries out trichomes and terpenes. The ideal relative humidity for cannabis storage is 55-62%.
Air Oxygen exposure oxidizes cannabinoids and degrades terpenes. Minimizing air exposure is crucial for long-term storage.
Best Storage Methods
Glass Mason Jars The gold standard for cannabis storage. Glass is non-porous, does not affect flavor, and provides an airtight seal. Use opaque or dark-colored jars to block light, or store clear jars in a dark place.
Humidity Control Packs Boveda or Integra Boost packs maintain precise humidity levels inside your storage container. The 62% RH packs are ideal for cannabis flower.
Vacuum Sealing For long-term storage, vacuum sealing removes excess air and significantly extends shelf life. Best for storing larger quantities.
What NOT to Do
Do not store in plastic bags. Static electricity pulls trichomes off the buds, and plastic can leach chemicals. Do not use the refrigerator. Temperature fluctuations cause moisture issues and trichome damage. Do not use the freezer for regular storage. Frozen trichomes become brittle and break off easily. Do not store near electronics that generate heat. Do not store different strains together — they will exchange moisture and aromas.
Storage by Product Type
Flower: Glass jar with humidity pack in a cool, dark place. Lasts 6-12 months. Edibles: Follow the product's storage instructions. Most last 3-6 months refrigerated. Concentrates: Silicone or glass containers in a cool, dark place. Lasts 6-12 months. Vape Cartridges: Store upright at room temperature. Lasts 6-12 months. Tinctures: Dark glass bottles away from light. Lasts 12+ months.
