Proper seed storage using silica gel and RH control

Seed storage in dry, cool, airtight conditions prevents ageing caused by oxidation from moisture and oxygen. This guide details a low-cost, effective method using a transparent airtight container with silica gel and RH meter to maintain 20–40% relative humidity. Seeds should be kept dry and sealed; open packages must be resealed or transferred to vacuum bags for larger quantities. Silica gel must be regenerated at 100 °C and cooled in an airtight container when RH exceeds 40%. The method supports seed viability and is ideal for home and small-scale use, part of the Liveseed Practice initiative under the Organic Farm Knowledge platform, with research from Wageningen University & Research (WUR).
