The other spot to check for mold in above your insulation aroung the cold air supplies. The moisture condenses above the insultation on the underside of the subfloor. Closing the crawl after putting a good vapor barrier on all of the earth, and maintaining 55% RH will fix all of that.

It's worth investigating. It will improve the comfort level in your home. The cost to operate the Santa Fe keeping your crawlspace dry and providing fresh dry air to your home will be less than a cheap resid. dehu dealing with the crawlspace. The Santa Fe is also more durable. I will come back with the thread with the data on ventialtion and energy useage. Regards TB
Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
