Small-scale seed drying methods

Drying is essential for the effective banking of orthodox seeds. Seeds should be dried to approximately 15% equilibrium relative humidity (eRH) before long-term storage. This allows the seeds to tolerate freezing, increases longevity in storage, prevents attack by pests and pathogens, and postpones germination.The choice of drying method depends on the projected yearly seed intake. A purpose-built dry room may be the most suitable option for drying large quantities of seeds. This information sheet describes various lower-cost drying options that may be more appropriate for small-scale seed banks.
