Also, it will grow if it is put in a dampish, wet, and place without a lot of light.
I actually did my last year's science fair on this... In theory, the store-bought bread will mold more slowly than the bakery bread. This is because the store bought bread is baked with all kinds of preservatives to give it a longer shelf life. However, most bakery breads are not.

The hypothesis that store-bought bread molds faster than bakery bread may stem from the preservatives and additives used in store-bought varieties. These preservatives can create an environment that promotes mold growth or affect the bread's moisture content. Conversely, bakery bread, often made with fewer preservatives and more natural ingredients, might have a longer shelf life. Additionally, differences in packaging and storage conditions could also influence mold growth rates between the two types of bread.
any bread molds after about a week if you want it to mold faster keep it damp...if you want it to mold less keep it dry...little fun fact no preservative wheat bread molds the fastest
