Seed Viability Longevity

Seed viability longevity refers to how long cannabis seeds remain capable of germination under proper storage conditions. Environmental factors—temperature, humidity, light exposure, and oxygen levels—directly impact how seeds age. Seeds stored in cool, dark, dry conditions (typically 4–10°C with <10% humidity) commonly demonstrate extended viability, sometimes remaining viable for several years. Conversely, seeds exposed to heat, moisture, or light degrade more rapidly, often losing viability within months. Breeders and seed banks routinely assess and document viability rates as part of quality control and preservation protocols. Understanding seed longevity is essential for breeding programs, genetic archives, and long-term seed banking strategies.

Breeders working with seed banking and genetic preservation track viability metrics to maintain breeding stock integrity and plan multi-year projects. Seed longevity data informs storage protocols and helps identify which seed lines require regular regeneration versus those stable for archival purposes.
