I've found a really easy and also cheap way to make a desiccant pack. You can do your own variation of it but this is really simple and cheap, to me thats the magic word. First get a pack of coffee filters 12 cup is perfect for regular storage cans. Next I found you can get silica gel (same ingredient/stuff that is in the expensive packs already made) really cheap, cheapest I've found that is pure stuff is stuff in the link. You can take a couple tablespoons of this and put in 1 coffee filter and staple it closed roll up filter to prevent leaks. You can make these bigger if you can get bigger stuff to put it in, I hope this helps you with storage of large amounts of materials....
