Seed Storage Conditions

Seed storage conditions refer to the environmental parameters—temperature, humidity, light exposure, and oxygen levels—that preserve cannabis seed viability and genetic integrity over time. Proper storage slows metabolic activity and protects seeds from degradation, mold, pest damage, and premature germination. Breeders and seed banks commonly maintain seeds at cool temperatures (32–50°F / 0–10°C), low humidity (5–10% RH), and in darkness or opaque containers to extend dormancy. Improper storage accelerates aging and reduces germination rates, making storage protocol a critical consideration in seed collection and breeding programs. Understanding these conditions is foundational for preserving rare or heirloom genetics across generations.

Professional breeders rely on controlled seed storage to maintain genetic libraries, preserve F1 hybrids, and protect backcross lines from environmental stress. Seed banks that serve breeding communities prioritize strict environmental monitoring to ensure consistent viability across multiple growing seasons.
