Seed Aging

Seed aging refers to the natural biochemical changes that occur in cannabis seeds over time during storage, affecting germination rates, vigor, and viability. Unlike volatile terpenes that develop during plant growth and flowering, seed aging describes degenerative processes—primarily oxidation and moisture loss—that impact the seed's ability to produce healthy seedlings. Older seeds may require pre-germination treatments (soaking, scarification) to improve sprouting success. Breeders and seed banks monitor seed viability through germination testing to ensure genetics remain viable across storage periods. Proper storage conditions—cool, dark, and dry environments—can slow aging processes and maintain seed longevity for years.

Seed preservation and longevity testing are critical for maintaining breeding lines and ensuring genetic stocks remain viable across breeding cycles. Breeders track viability curves to determine optimal storage protocols and identify when seed lots should be regenerated to maintain line integrity.
