Closets often have mold growth, especially if clothing is stored damp or dirty. Conditions for Mold Growth Molds grow on organic materials such as paper, leather, dirt and soap scum. They grow best at warm temperatures, between 77 and 86 degrees Fahrenheit, although they can grow in temperatures between 32 and 95 degrees.
