Regular oven set at its lowest temperature will do the trick, too. We save and use the silica crystals in the little packets that come in all sorts goods you buy. We throw a few in the bottom of a 5 gallon bucket, gallon jar, or other sealable container, put in our seeds and seal it up. Our seeds spend the Michigan winter in an unheated attic, but in early spring, before the attic heats up, head down to the then cooler basement (where the moisture is higher and the silica gel is even more important).
