I have a place in north Georgia. Half the building in above a crawl space and the other open to below ground. The crawl space has 6 mil plastic on floor to cover clay dirt.Walls are block. Ceiling has 6 inch insulation with vapor barrier facing up.The furnace is in this space. Its a vacation home so its not lived in alot.I have been reading about crawlspace ventilation units that mount in the foundation vents to draw out the moisture.Smartvent was one of them.Any opinions?

Then under research or resources there is a bunch of informatin.

Also google Conditioned Crawlspace.

In general you want ot SEAL the crawlspace and not not allow in outside air.

The the bottom and walls are SEALED (that means more than just puting down plastic, but the joints need to be sealed). Then any moisture that get is from the outside. And the relative cool ground cause the RH to increase.
