Freezing seeds and then recovering them depends on the moisture content of the seeds when they are frozen. Too much and the freezing moisture expands so much that the outside surfaces of the seeds cracks and then freezing drying takes place and the germplasm is destroyed. Seed Banks reduce the internal moisture levels to a very low percentage and this prevents the "expansion destruction".
Many of us here in the "amateur" world put our seeds into the freezers and hope for the best. I, for one, will not allow my seeds to be subjected to those killing temps. Room temperature in paper or hermetic sealed containers (repurposed medicine bottles) is the only methods I use.
