Interesting, thanks for sharing.
For me, the peroxide is also to help sanitize the perlite and baggy within which the seeds are going to be stratified. Despite this, an indicator of contamination for me is that the perlite turns a yellowy/brown color after stratification and placement to room temperature, and those seeds will be mushy due to contamination. If it stays pure white, it is a good sign all is well.
But even many of the good ones will no longer pass the "squish test", I think.
I have a ton of spare seeds I can test this with, actually.
I can do the squish-test before and after cold damp stratification splitting the seeds into experimental groups, if I remember. If they explode in my fingers using the same pressure as when they were dry, I will be able to ascertain that.
I like the idea of the paper towels, but again would probably need peroxide to sanitize them first (or perhaps I can microwave them just before use, or use a UV-lamp?). Or do you guys have a source of sterile paper towels?
