Seed Storage Conditions

Seed storage conditions refer to the environmental parameters—temperature, humidity, light exposure, and container type—that affect cannabis seed viability and longevity. Proper storage preserves germination rates and genetic integrity over extended periods, making it a critical consideration for breeders, seed banks, and cultivators maintaining seed libraries. Seeds stored in cool, dark, dry conditions (typically 4–10°C and 20–30% relative humidity) commonly retain viability for years, whereas exposure to heat, moisture, or light accelerates degradation. Different seed types and genetic lines may show varying sensitivity to storage stress. Understanding storage protocols is essential for breeding programs that rely on long-term seed retention and germplasm preservation.

Breeders working with rare or experimental genetics depend on reliable storage methods to maintain seed banks across multiple seasons and generations. Seed stability under various storage conditions is often evaluated during line selection to identify which genetics show robust longevity, informing decisions about preservation strategies and breeding stock management.
