yeah i dry mine on wax paper (Have had problems with them sticking) for a long time. And then I put them in a closed container all by themselves, not with any prior dried seed’s. I had a whole batch of zucchini seeds ruined one year.
That’s why I use the top of the Frig. It’s a little warmer up there and they dry out better.
The plates ( I turn the top one over so that it’s not touching the bottom one. But, it allows me to stack them up too so that I don’t run out of room, and yet lets enough air circulate.
