At what humidity does mold start to grow?

Subsequently, one may also ask, will mold grow at 55 humidity?
Humidity levels above 55 percent can allow mould to grow, although levels of 70 percent are more ideal for mould growth.
Secondly, what humidity level kills mold? To kill mold, you need to get the humidity below 50%, and around 35% is optimal. If it's a mold problem in your basement, having a contractor install vapor barriers around the outside of the foundation of the house is probably the best long-term option.
Thereof, what temperature and humidity grows mold?
Warm, humid conditions are ideal for mold growth. Most molds need temperature of 70 degrees Fahrenheit (20 degrees Celsius) or more to grow. Air conditioners to regulate the temperature of your house can help prevent mold growth.
How does humidity affect mold growth?
Mold needs water to grow; without water mold cannot grow. Molds prefer damp or wet material. Some molds can get moisture from the air when the air is very damp, that is when the relative humidity is above 80%. The high humidity makes surfaces damp enough for mold to grow.
