BUDWEEDSEEDS

Growers disagree about whether a refrigerator or a freezer is the better place for a seed collection. Discussions of how to store cannabis seeds long term often note that freezing can extend viability for a decade or more, but only if the seeds are thoroughly dry beforehand, since internal moisture forms ice crystals that rupture cells. Refrigeration is more forgiving and suits storage of several years. Whichever is used, frequent door opening should be avoided.
