Detailed explanation-1: -Mold requires water, food, and oxygen to grow. It also requires an environment with a temperature it can survive.
Detailed explanation-2: -Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.
Detailed explanation-3: -Different types of fungus or bacteria require different amounts of water (in vapor form) to reproduce and grow. The majority require relative humidity (RH) of 60 percent or more, though some can survive and multiply in >20 percent RH.
Detailed explanation-4: -If there are no cold-condensing surfaces and the relative humidity (RH) is maintained below 60 percent indoors, there will not be enough water in those materials for mold to grow. However, if the RH stays above 70 percent indoors for extended periods of time, mold will almost certainly grow.
