Rationing A Pack Over Years

Germinating an entire pack of regulars in one run gives the best selection, but keeping a few seeds back is cheap insurance against losing the line to a bad germination, a pest wipeout or a house move. A common split is two thirds now and one third stored properly. The trade off between a bigger sample and a safety reserve is weighed on https://breederregularseeds.com, and it favours holding some back for anything rare. I lost a line to a single power failure, so I no longer argue.
