Vacuum Sealing Methods

Vacuum sealing is a preservation technique used by seed banks and breeders to extend the viability of cannabis genetics in storage. The method removes oxygen from sealed containers, slowing oxidation and degradation of cannabinoids, terpenes, and seed viability over time. Proper vacuum sealing typically involves food-grade bags, heat-sealed edges, and cool, dark storage conditions. Breeders and seed curators working with heirloom or rare lineages commonly employ vacuum sealing to maintain genetic integrity across generations. This approach is particularly relevant for long-term conservation of seed libraries and breeding stock.

Breeders maintaining seed banks rely on vacuum sealing to preserve genetic material between breeding cycles and to archive rare or foundational crosses. Consistent seed viability through proper storage directly impacts the reliability and stability of breeding programs over multiple years.
