Does mold grow faster in the light or dark?

Mold can grow in both light and dark conditions, but it tends to grow faster in dark environments. This is because darkness provides the ideal conditions for mold growth, including warmth and humidity. Mold spores can germinate and grow quickly in dark, damp areas, and they can spread easily through the air or on surfaces.

While mold can grow in light, it does not grow as quickly as it does in darkness. This is because light can help to inhibit the growth of mold by damaging its spores and mycelia. Ultraviolet (UV) light, in particular, is effective at killing mold spores. Therefore, it is important to keep areas clean, dry, and well-lit to help prevent the growth of mold.
