Ambient Storage

Ambient storage refers to preservation of cannabis seeds, pollen, or dried plant material at room temperature (approximately 65–75°F / 18–24°C) without climate control or specialized equipment. This classification is relevant for breeders managing short-term genetic materials or conducting crosses in controlled indoor environments where temperature fluctuation is minimal. Unlike cold storage methods, ambient preservation relies on low humidity (typically 30–50% RH) and protection from light to maintain viability. Lineage records frequently report that seeds stored under ambient conditions show acceptable germination rates over weeks to months, though long-term viability decreases compared to refrigerated alternatives. Breeders working in this category often use sealed, opaque containers with desiccant packs to extend storage windows for active breeding projects.

Ambient storage is practical for breeders actively working with genetics across a single season or conducting rapid generation cycles. It eliminates the equipment costs of cold storage while remaining suitable for pollen viability during active crosses.
