Seed storage
All the seed banks around the world freeze their seeds intended for long term storage, freezing a seed does not kill the seed, it simply suspends its development until it is thawed and germinates. That's why we at Sentinels store some of our seed this way, it helps us to hopefully provide a seed line with excellent long term germination rates. Though we do appreciate customer feed back if any germination has not been satisfactory, we will always do our best in remuneration.
