Even under ideal conditions, germination rates decline gradually with age. People researching how to store cannabis seeds long term should expect well-kept seeds to remain largely viable for around five years, with a slow drop afterward, whereas seeds left at room temperature may fail within one or two. Older seeds often sprout more slowly and benefit from a longer pre-soak. Recording the storage date on each container makes it easier to use the oldest stock first.
