Storing tins in a damp environment

[Highlander]

Interesting point about freezing,... I dont believe mine would reach anywhere near freezing, but for the future I would like to know the answer to this.

Off the top of my head, I think if I was going to store where freezing might be a problem then I think that I might change my containers from plastic to the polystyrene fish boxes,... or at least protect the plastic containers with something like garden fleece, that's designed to protect plants from freezing
