I have seeds from years ago in a ziploc bag and stored on a shelf in my grow room. So far they germinate just as good as fresh ones. I'm holding on to them but I haven't been using them since they have males too and I've been getting fresh (female) seeds anyway. Eventually I'll end up doing mother plants for clones, but I like the seed method for now. I'd love to be able to cycle a few different strains for a bit and stock up. Anyway, yeah I'm excited to finally be using the bags. I had some for a while but I didn't see a point in using them for an oz or less. Messed up a bit and hurt my yields. Hoping for better luck on this next harvest.
