rick- keeping humidity down?

Hi Rick, I will pick up your book for sure just on that topic of animals in the greenhouse alone, im glad to hear the greenhouse as a barn works well. Im located in maritime canada so we get a mix of summer weather both dry and humid.

I had thought of using a concrete envelope (walls, floor, roof, etc) with lots of insulation and earth berm protection for the north and east sides, and using the climate battery concept to pump the warm moist air underground in a gravel filled concrete envelope, insulated from the earth to minimize heat transfer to the ground, for storing the heat for winter use. Whats your thoughts on that keeping the summer humidity down?
