Protogro's worm food is a specialty blend of grains, vitamins, and nutrients to provide all the digestive necessities for your worms to grow plump and healthy, leading to a stabilized worm farm and burgeoning worm nursery! Regular vegetable scraps have a tendency to also grow unwanted fruit flies. By feeding worms our worm food, not only do they get all the nutrition and energy they need in a controlled, time-released fashion; all without the annoyance of little, unwanted bugs! Happy Worming!
