I read the title of the thread and the first page or so, then jumped to the end and it appears to have gone well off topic. 12,116 posts and I wonder how many are about members collections of seeds.
Anyway, I'll admit I have a growing stash of seeds. Last count was 163 with predominately different strains for the most part (have a couple of strains that were 5/8 packs, but mainly pick 'n mix). Only got a PE and PPP on the go at the moment. And I understand that seeds do have a shelf life. Had a load of bag seed I tried to germ this time last year and of 30 + seeds none popped. They are 15 years old (at least) though
