Storage And Humidity Control

Storage and humidity control are critical preservation practices in cannabis breeding and seed banking, directly affecting terpene retention and genetic viability over time. Terpenes are volatile organic compounds that degrade when exposed to heat, light, oxygen, and fluctuating humidity levels. Breeders and seed banks commonly maintain temperatures between 32–41°F (0–5°C) and relative humidity of 20–30% to slow terpene oxidation and preserve aromatic profiles across generations. Proper storage in airtight, opaque containers—often with desiccants or inert gas—helps stabilize both cannabinoid and terpene composition in archived genetics. Inconsistent humidity can promote mold, mildew, and bacterial activity, compromising both sample quality and breeding records. Understanding storage science is essential for maintaining strain authenticity and terpene expression in long-term genetic libra

Breeders rely on controlled storage to maintain stable parent genetics and accurately track terpene expression across generations. Proper preservation ensures that aromatic and volatile profiles remain consistent when selecting for specific terpene lineages in breeding programs.
