Ambient humidity and seasonal behavior changes

Thanks Dave awesome advise as usual.

For me it was very significantly different in my Vino's, the coolers where not impacted and it makes sense after reading your OP as they are a fully sealed environment. In the winter Calgary gets a wide variance of temps and teh RH is low. My Vino's dropped 5 points over night when the temperature bottomed out and they had not moved since maybe July and required hardly any maintenance. Now it is a daily watch to ensure that the beads are doing there thing.

I think this is the main reason I like to be well above the minimum beads for the volume as it allows the beads to maintain equilibrium in larger swings.
