How you store your cannabis seeds will depend on how long you plan to store them for. For short-term storage, cannabis seeds can be stored in a dark cupboard with stable temperatures. If, however, you plan to store your seeds for longer periods, consider storing them in an airtight container along with a desiccant, such as silica gel, inside your refrigerator. Note that seeds are best stored in frost-free fridges, as they are less humid.
