The Heirloom Organics exclusive VAULT™ method of seed preparation produces up to TWICE the SHELF-LIFE of “normal” seeds. The VAULT™ system is based on the seed preparation techniques pioneered at the National Seed Storage Lab of the US Department of Agriculture in Fort Collins Colorado.

The VAULT™ system uses an advanced moisture-modification and double-sealing process to ensure maximum EXTENDED SHELF-LIFE. Moisture-management packets are sealed inside all inner packages to maximize sustained seed germination rates over the longest period of time. All Heirloom Organics Main Packs (Seed Vault, Family, Homestead and Farm) as well as our Grains Pack are then ALSO sealed into heavy-duty, water-proof/moisture-proof , open-and-reseal green pails for maximum protection.

Seed Viability Testing (pictured at right) is used to determine the germination rate of seeds. High germination rates of seeds (% of seeds that sprout into seedlings) is the measure of successful seed storage. Seed Viability Testing is used after seed storage to evaluate the methods for ultra long-term storage.
