Does mold grow faster on store bought bread or homemade bread?

Oh, dude, mold doesn't care if your bread is store-bought or homemade. Mold is an equal opportunity invader, it'll happily chow down on any bread left out too long. So, whether you're munching on fancy artisanal loaves or budget-friendly supermarket slices, just make sure to store them properly and eat them before they turn into a science experiment.
