Seed Storage Standards

Seed storage standards refer to the documented practices and environmental conditions breeders and seed banks use to preserve cannabis seed viability over time. Proper storage typically involves controlling temperature (often 4–15°C), humidity (5–10% relative humidity), light exposure, and oxygen levels to slow metabolic activity and maintain germination potential. Well-preserved seeds can retain viability for months to years, making standardized storage critical for breeding programs, genetic conservation, and commercial seed production. Different seed types—feminized, regular, autoflowering—may have slightly different longevity profiles depending on production method and genetic background. Documentation of storage conditions is essential for tracking seed age, potency stability, and breeding reliability across generations.

Breeders rely on consistent seed storage protocols to maintain accurate genetic records, ensure repeatability across growing cycles, and preserve rare or foundational genetics for future crosses. Seed banks and preservation initiatives use these standards to support long-term breeding work and genetic diversity conservation within cannabis populations.
