Did you freeze your seeds after drying them?I planted a seed around 7 months ago and a bit over a month ago it germinated. took around 5 &1/2 months to germinate and it was not an old seed. strain is jamazari-haze that I made.
Years ago (50s and 60s), the old gardeners swore that storing the seeds in the deep freeze, improved the rate and speed of germination.
I do it still....not how much or if it helps..... just the way I learned to do it.
