I as well used to use rice until someone I was following on IG made a post about rice and parasites. It was a macro photo shot of rice with all these gnarly little dudes running around. The intention of the post was to warn people about where they source their rice for seed storage. He went on to say that he uses organic basmati rice for storage. Now take that for whatever its worth, but it at least made me second guess putting rice naked around my seeds.
The desiccant packs are a nice touch though, might have to steal that from you. Akbeanbrains stored his beans in a freezer for decades and has 99% germination rates when going through those old packs. ?♂️ I think freezer storage is fine as long as you don't mess with anything. A garage storage fridge where you can put them in there and not touch it until its needed.
