How does mold growth work?
Mold growths, or colonies, can start to grow on a damp surface within 24 to 48 hours. They reproduce by spores – tiny, lightweight “seeds”- that travel through the air. Molds digest organic material, eventually destroying the material they grow on, and then spread to destroy adjacent organic material.
