To start the process, stock pile materials, enough to generously fill one of the three sections of this unit. After a week, start to check the temperature of the pile daily with your hand or a soil thermometer. Follow this temperature cycle and turn the material into the final section when the temperature rises and then drops again. In a span of approximately three weeks to a month, you can have usable compost. Store this compost in the third bin until needed.
Construction requires basic carpentry skills and tools.
Material costs will vary with current lumber costs. Costs will be less if recycled materials are used. Repeat this process to make three more frames. Check that each frame is square and stretch hardware cloth across. Set up dividers so that they are equally spaced approximately 3-feet apart and parallel to one another.
