I have 5-6 large 40 gallon totes with red wigglers that live underneath my aquaponic growbed. I prefer worm composting over normal compost because I do not have the room for a large heap. I purchased the brown rubber made containers from lowes and drilled air holes in the side and drainage holes in bottom. You can start your bin with shredded cardboard, newspaper, or a layer of leaves. Take some sand and dress the top of that to aid in the digestive process since they don't have teeth. From there you can add kitchen scraps but stay away from citrus, meat, grease... Want to speed it up; blend your scraps with water and feed them that way. It also keeps it moist. After a few months you will have "black gold". If your worm population gets to big add them to your garden. If you want to be super hardcore catch the leachate that comes out when you water them and brew that as compost tea.
