For those of us that are fanatical about our seeds, storing them becomes a necessity. The best way to ensure you'll have them for years to come is to keep them airtight. Try heading to your local military surplus store for a few affordable options.
Although there are other retail options, we love using air tight trunks, cabinets and ammunition cans from our local military surplus store. Even small towns have military surplus lurking somewhere and since military grade products are meant to keep the elements out, they're a perfect vessel for keeping your seeds safe and un-germinated!
