Humidity is how much water vapor is in the air. When the air has too much water vapor, we call it high humidity. When there’s not enough, it’s low humidity.
Mold loves wet and warm places. High indoor moisture levels create the ideal environment for mold spores to grow. These spores float in the air and land on organic materials like wood, drywall, or even dust.
If the surface temperature and the ambient conditions are right, mold starts to grow fast. Some mold growth prediction models show that mold can grow in just 24 to 48 hours if the conditions are right!
