I have about a 1900 sqft. crawlspace that had 80% humidity with fungi growth. I expected a dehumidifier to be delivered today, so yesterday I prepared the crawlspace and sealed of all openings. Dehumidifier will not be shipped until 5-7 days.
Data log today reads 90.1% and is slowly rising.
Should I open crawlspace door and direct a fan to pull the humid air out, or will that spread more fundi spores around?
I gotta do something.
