Store cannabis airtight, cool 60-70°F, dark, humidity 55-62% RH. Well-stored cannabis retains potency + terpenes 6-12 months. Poor storage degrades to weeks. UV + heat destroy terpenes fastest. Boveda + Integra Boost packs maintain ideal RH automatically.
Cannabis storage affects potency, terpene profile, and shelf life. Properly stored cannabis flower retains its cannabinoid potency and terpene profile for 6-12 months; poorly stored cannabis can lose terpene-driven flavor within weeks and lose THC potency to oxidation within 3-4 months. The four storage variables that matter most are humidity, temperature, light, and air exposure. This guide covers each variable with practical recommendations sourced from cannabis cultivation + post-harvest research.
Cannabis stored too dry (under 50% relative humidity) becomes brittle and harsh; too wet (over 65% RH) becomes susceptible to mold. The ideal range is 55-62% relative humidity. Two-way humidity-control packs (Boveda 62%, Integra Boost 62%) maintain this range inside an airtight container automatically. Place one pack per ounce of cannabis. Replace packs when rigid (every 2-4 months).
Cannabis terpenes evaporate at relatively low temperatures (some as low as 70°F / 21°C). Store cannabis at 60-70°F (15-21°C). Avoid temperatures above 75°F. Do not store cannabis in a freezer — freezing can damage trichome glands; the rehydration cycle from frozen to room-temp accelerates terpene loss. A cool dark cabinet at room temperature works well for most home storage.
Ultraviolet light degrades cannabis terpenes faster than any other variable. Direct sunlight can degrade a fresh batch's terpene profile within days. Store in opaque containers (amber glass + UV-resistant plastic), or keep clear containers in a dark cabinet. Avoid storage on countertops near windows.
Oxygen exposure oxidizes THC to CBN (a milder, more sedating cannabinoid) over time. Airtight containers slow this conversion. Vacuum-sealed bags or glass jars with airtight gaskets (Mason jars work well) are preferred. Avoid plastic baggies for long-term storage — plastic outgasses and absorbs terpenes.
For best long-term preservation: opaque glass jar (Mason or Boveda-branded) + Boveda 62% RH pack + cool dark cabinet at 60-70°F. This setup preserves cannabis potency + terpene profile for 6-12 months. For short-term storage (consume within a month), an airtight plastic container in a drawer is acceptable. Keep cannabis out of reach of minors regardless of storage method — child-resistant packaging is required by MN OCM at point of sale.
