I agree with you Kayleigh. Diploid seeds seem to keep better and older seeds can be viable no matter how you store them. In my test from last year with two year old seeds, about half tet and half dip, all the dips produced seedlings and none of the tet seeds sprouted.
I have lots of seeds stored in small cups in a back room as well. My real test will come this spring when I make some grow boxes and mass plant all my old seeds to see what I get to sprout. I am not going to take time to mark them except dip and tet.
I got out bags of seeds from past years and sorted to find some that look like they may be OK. I am talking about thousands of seeds from 2010 to 2014. I only found a few tet crosses from 2010-2013 that look like they could possibly be good. I have more than 100 dip crosses that look like they could be good seeds. The 2014 seeds look good.
I will have to see if any 2010 seeds are good. It will surprise me if any sprout.
