Moisture And Storage

Moisture and storage conditions are critical factors in cannabis preservation, directly affecting terpene retention and cannabinoid stability over time. Environmental humidity, temperature, and light exposure all influence how volatile aromatic compounds degrade or remain intact in dried flower and extracted material. Proper storage—typically in cool, dark, airtight containers with relative humidity between 55–65%—helps slow terpene evaporation and oxidation. Breeders and seed banks rely on controlled drying and curing protocols to preserve strain-specific terpene profiles for accurate phenotype assessment and lineage documentation. Improper storage conditions can lead to significant terpene loss within weeks, altering the chemical signature that defines a strain's genetic expression.

Breeders preserve mother plants and working lines by maintaining strict humidity and temperature controls to keep terpene profiles stable across generations. Seed banks store genetics in low-moisture, refrigerated conditions to maintain viability and prevent terpene degradation that could mask or misrepresent a strain's true aromatic character.
