Understanding Mold Growth

Mold is a type of fungus that reproduces via spores, which are tiny and lightweight, allowing them to disperse through the air. Mold spores are virtually ubiquitous, present both indoors and outdoors. However, mold requires certain conditions to grow and multiply, including:

  • Moisture: Mold needs a damp environment to thrive. Leaks, high humidity, and condensation are common sources of moisture that can lead to mold growth.
  • Organic Material: Mold feeds on organic materials such as wood, paper, and fabric. These materials provide the nutrients mold needs to grow.
  • Warmth: Mold grows best in warm temperatures, typically between 77°F and 86°F (25°C and 30°C).
  • Oxygen: Mold requires oxygen to grow, but it can survive in low-oxygen environments as well.
