Preservation Temperature

Preservation temperature refers to the optimal storage conditions required to maintain terpene stability and cannabinoid integrity in cannabis plant material, seeds, and finished products. Terpenes are volatile organic compounds that degrade when exposed to heat, light, and oxygen, making temperature control a critical factor in genetic preservation and breeding programs. Most cannabis geneticists recommend storage between 32–68°F (0–20°C) for long-term stability, with freezing (below 0°F / -18°C) preferred for seed banks and genetic repositories. Fluctuating temperatures accelerate oxidation and terpene loss, degrading both flavor profiles and the chemical signatures breeders use for phenotype identification. Understanding preservation temperature is essential for seed viability, maintaining breeding lines, and ensuring accurate genetic documentation across generations.

Breeders maintain controlled cold storage for parent plants, seeds, and clones to preserve terpene profiles used in strain selection and lineage tracking. Consistent preservation temperatures directly impact seed germination rates and genetic stability when maintaining breeding stock across multiple seasons.
