Proper seed storage conditions are cool and dark. The moisture content within the seed greatly affects germination rates. Seeds should be stored in their original packaging in a cool (below 50 degrees Fahrenheit), dark place where their moisture content will stay relatively stable. Courtesy of High Mowing Seeds
