Storage Conditions

Storage conditions refer to the environmental factors—temperature, humidity, light exposure, and oxygen levels—that affect cannabis seed viability and plant material preservation. Proper storage is critical for maintaining genetic integrity, cannabinoid and terpene profiles, and seed longevity across breeding cycles. Breeders and seed banks employ controlled environments to prevent degradation of phytochemical compounds and preserve cultivar traits over time. Temperature stability (typically 32–50°F for seeds, 60–70°F for dried flower) and relative humidity (30–62% RH) are standard preservation benchmarks in professional cultivation and archival settings. Inadequate storage—exposure to heat, moisture, light, or oxygen—accelerates oxidation and microbial colonization, compromising both genetic material and chemical consistency across generations.

Breeders maintain seed banks and mother plant collections under controlled conditions to ensure trait consistency and viability across multiple growing seasons. Proper storage protocols are essential for preserving rare or recessive genetic markers and enabling long-term breeding programs without unintended genetic drift.
