Vacuum sealing seeds

I'd be concerned with physical damage to some seeds, and perhaps the moisture trapped in plastic bags while they're still empty. I posted this a couple of weeks ago - check it out:

up some silica gel packs (the kind you can heat in the oven to dry and reuse) at a gun shop, and you've got yourself a system. Do NOT buy the drying crystals sold in boating supply stores - they're usually not silica gel. The ones I use come in perforated metal boxes about the size of an Altoids tin. They have a clear plastic peephole so you can see when the crystals change color and need to be baked. When I can get to my gun box (later - after my honey wakes up - don't want to make a racket in the bedroom), I'll post the name stamped on the things. You should be able to find them online.
