Reading a couple different things, the best way to store seeds is in the package in a mason jar filled with rice in the freezer correct?!?
Rice or silica packet(s)
I store my seeds in a safe with a silica desiccant in the safe to absorb moisture like this one. My safe is small, so anything larger would be overkill.
All my seeds are in the respective containers and then in a freezer bag with silica packs and then in the fridge. No need for them to be in a freezer tbh
