We have used some of those moisture absorbing "buckets", which work on a small scale but they do add up $-wise and probably cannot handle a larger volume of air on a sustained basis. Keeping ventilation going is certainly part of the answer and I wonder if installing a dorade or two, or a solar-powered vent or something of that sort might be part of the solution.

Over to you guys out there!
Ventilation if it's warm enough.

Minimizing humidity from cooking, showers and heaters.

Also these can operate on 12V (they use a 110Vac to 12Vdc converter).

They draw about as much as running lights and can remove 4-30 oz/day, depending on the temperature. About 20x faster than a CaCl2 bucket.
