Hi Rick,
Thank you for posting about your method of storing seeds.
Sometimes I will put the seeds/heads in regular letter (paper) envelopes to make sure they dry out real good. I've been too anxious and put them in the plastic bags or jars before, too many times they just end up moldy because they weren't completely dry! Never thought about those little silica packs that come in so many things - I've been saving them to use for something LOL!
