Your initial analysis may say something like 7,000 mold spores per cubic meter of air for a humid vented crawlspace during the middle of the summer, with visible mold and then you may seal it all up, install a dehumidification system, or do waterproofing and 8 weeks of dryness later after your mold sampler has crawled through the now dusty crawlspace knocking everything down and picking everything up to start your follow up test after the work done, you may have solved the humidity problem, made the space much more inviting and clean, but get an analysis back that there are 77,000 mold spores to the cubic meter. Ideally an old nasty crawlspace would be sealed in February when it is bone dry to start with. If you cool it down to below 78.8F, the relative humidity level goes to 100% and the water condenses (The dew point). In simple terms, evaporative cooling works like this your body sweats, and through the evaporation of your sweat, your body cools. It would feel much more "humid" on the 80 degree day with 50% relative humidity than on the 30 degree day with a 100% relative humidity. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%. The active drying is absent (if you are using the supply air for the crawlspace drying mechanism) and it is likely humid and raining during those times. Heavy sweating.
