I have a hermanns tortoise and am trying to learn how to grow him food. I figured the easiest way is sprouts. Trust me I have tried many things and I really just don't have a green thumb and kill almost everything. I am wondering if sprouts of any kind would be ok to feed him? Such as alfalfa, broccoli or radish sprouts are some that I've seen. Any suggestions on if this is ok to feed him?
