Turn it or mix it every few weeks. The more often you mix it, the faster it will decompose. This is how in-vessel composting systems process compost in a week or two. Vermicomposting is extremely small-scale, and easy to do in a dorm room or apartment. You can choose a shoebox-sized container or a larger container that can hole several gallons, depending on the amount of space you have available.
Red wigglers are able to compost more material.
Use the drill or hammer to put holes in the lid of the container. Put at least 15 holes if using a shoebox-sized container, and many more holes is using a larger container. Layer an inch of gravel on the bottom of the container, fill the rest of the container with the potting soil. Mix in the worms and some organic material. So it's okay to store them outside, but bring them inside during the colder winter months.
