Seed Bank Practices

Seed bank practices refer to standardized protocols breeders and preservationists use to maintain genetic integrity, viability, and stability across cannabis seed collections. These include controlled storage conditions (temperature, humidity, light exclusion), documentation systems for tracking lineage and generation numbers, and periodic viability testing to ensure seeds remain viable for future cultivation. Proper seed banking distinguishes between seed types—regular, feminized, and autoflowering—and accounts for how each responds to long-term storage. Well-managed seed banks serve as repositories for heirloom genetics, experimental hybrids, and research material. The practice is foundational to breeding work, allowing breeders to reliably access parent stock and maintain consistency across generations.

Breeders rely on robust seed banking to preserve parental lines, stabilize trait expression across multiple generations, and prevent genetic drift or contamination. Proper documentation enables reproducible crosses and helps breeders track which genetics produced desired phenotypes.
