Bread with Peanut Butter.
wet bead
Pasturage Farm's Marble Rye Swirled. It molds in about 2 and a half weeks
by letting air get to it Also, it will grow if it is put in a dampish, wet, and place without a lot of light.
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
i think multigrain will grow faster because it has more chemical and proteins.
