Cryogenic Storage

Cryogenic storage refers to preservation techniques using extremely low temperatures (typically below -150°C) to maintain cannabis plant material, extracts, and genetic samples over extended periods. This method slows metabolic processes and degradation of cannabinoids, terpenes, and other plant compounds, making it valuable for seed banks, research institutions, and breeders maintaining genetic libraries. Proper cryogenic preservation can retain viability and chemical profiles for decades, though protocols vary by material type—whole plants, seeds, pollen, and concentrates each require specific handling. The technique is distinct from standard freezing and requires specialized equipment and expertise to prevent ice crystal formation and cellular damage. Breeders and genetic repositories increasingly rely on cryogenic methods to archive rare or foundational genetics.

Breeders utilize cryogenic storage to preserve elite parent genetics, pollen from prized male plants, and seeds from limited crosses without degradation between breeding cycles. This enables long-term genetic stability and allows breeders to access archived genetics years or decades later without loss of potency, terpene expression, or germination rates.
