Moisture Content Storage

Moisture content in stored cannabis is a critical parameter affecting preservation, potency stability, and mold risk rather than an aroma itself. Proper storage moisture (typically 55-62% relative humidity for long-term preservation) helps maintain volatile terpene profiles and cannabinoid integrity. Excessively dry material (below 40% RH) risks terpene loss and brittleness, while high moisture (above 65% RH) accelerates degradation and creates conditions favoring microbial growth. Breeders and seed banks monitor moisture during storage protocols to preserve genetic material and phenotypic expression across growing seasons.

Breeders use moisture-controlled environments during seed storage and mother plant preservation to maintain genetic stability and consistent terpene expression in subsequent generations. Proper humidity management in breeding facilities directly impacts seed viability, germination rates, and the reliability of phenotype replication.
