I have all my tobacco in a cupboard. Tins, mason jars, samples in plastic baggies.... some of it came already dry in the tin (Magnum Opus and Larry's Blend) and some of it is getting dry from simply being in opened tins with poor quality seals, also the stuff in baggies isn't well protected. I was wondering what my best bet is to get some moisture into this stuff. Would a simple bowl of water in the cupboard give off some ambient moisture and help things out a bit? Or do I need to rehydrate individual blends with some sort of dedicated device in each container?
