How do you store and save seeds?

Okay guys if I wanna start saving seeds from different strains how do I keep them usable and preserved 1-2 years.

Vacuum seal them, then put them in the freezer. That's your best bet.

A fridge or freezer will work...if they're simply in low humidity climates, seeds can remain viable for a decade or more.

I put my seeds in a plastic bag, put the bag in a film container and put in the refrigerator/freezer.
