This is a good to piece of information specially to the vapers who are hording for the next couple of years because of the FDA regulations.
I've been involved with a local history museum most of my life. There are lots of period artifacts, documents, etc. We try to understand the factors that promote deterioration and act accordingly. Storage solutions are driven mostly by the materials you want to protect.
Some people are hoping for 10-20 years for a vaping stash, including me, so I wonder how to get there without over spending or miscalculating.
1. My long term nic is in padded, air tight, 1 liter amber glass bottles kept at freezing temperatures to minimize exposure to light and oxygen. I'm confident that's good enough for 10 years. A 10 year supply for me is 250,000 mg which costs only $125. So I added a redundant supply from a different vendor in case the first batch spoils. If there is no spoilage and nic can actually last indefinitly, which nobody is really sure about, then I'm good for a silly long time for a trivial amount of money.
2. The atomizer I'm storing (and use every day) is a reletively simple rda. The rubber o-rings may get brittle over time but they are generic. The insulator around the center pin is simple enough that I can make them or have them made if they get brittle. The wire is trapped under a generic screw and nut.
3. That leaves the mods which will be removed from ratail packaging and kept in stable acid free materials of some kind yet to be determined. May be that's overkill but doing things right won't cost anything. Why mess around?
