HERDS AND HAREMS. Like all wild horses, the Pryor mustangs are herd animals living off the land in harems, dominated by the strongest stallions. According the Save the American Wild Horse organization, a dominant stallion, usually 6 years of age or older, will be in the company of one mare or a group of mares 24 hours a day, 365 days a year. He sires the offspring, and these foals are with their band for at least one year, usually two.
One Southern homeowner with a 1,500-square-foot crawl space was quoted $5,000 for one contractor to install CleanSpace and $3,000 for another contractor using DrySpace; another Southern homeowner was quoted $9,500-$12,000 to install CleanSpace in a 1,400-square-foot crawl space, and instead paid $1,700 for do-it-yourself DrySpace materials.
Calculate the cubic area of the crawl space by multiplying the length x width x height (in feet). Divide this number by 15 to determine the minimum CFM required to fully ventilate the space in 15 minutes. For example, this two-fan crawl space ventilator delivers 220 CFM and will ventilate a 3,600 cubic foot area in 15 minutes.
