I clean the seeds as much as possible, and air dry them for a couple of days. I then put them in paper packets and lable them for type and date collected. I put the packets in mason jars that have indicated desicant in the bottom. I then pull the air out of the jars with a vacume sealer, and then store the jars in a dark, cool location. For long term storage, I put the jars in the crisper section in my refrigerator, with a cover over the jars so that the light doesn' affect them.
