Seeds in cold storage
Once the seed has been dried to the required level it is packaged and placed in the cold room where it is kept at a temperature of -20°C.

The length of time that each collection can be stored for is fixed by the biology of the seed. Depending on the species, seeds may live decades, centuries and, in some cases, even millennia.
