Tumbling action turns these composters into efficient, compost-accelerating machines. Each batch starts with a balanced mix of ingredients and cooks until it's done, which can be as little as four to eight weeks. A batch composter is the fastest way to create compost, but it needs to be turned daily and checked for sufficient moisture. While one batch is cooking, you stockpile the materials for the next batch. The stockpile can be an open bin, pile or a continuous composter.
Best for: Gardeners who want to get more compost faster — and are willing to put in a bit more effort and planning.
