I've also never heard of gluing seeds. I don't know why you are going through all that trouble for bagseed. I hope the glue doesn't kill the seeds. In any case, you are probably better off buying fresh seeds with good genetics and the proper strain for your environment (i.e. indoor vs. outdoor) instead of frustrating yourself with old unidentified seeds. But, at any rate, the seeds will store for years. You can even put them in the fridge or freezer. Seeds are designed to survive the winter.
