The next generation of composting is now available. The Compost Wizard Double Tumbler combines some of the greatest features in our tumblers to create a compact tumbler that does it all. With compost tumblers, users are restricted to working with one batch at a time. The Double Tumbler overcomes this drawback by supporting two batches running simultaneously. Each 25 gallon chamber is separated and can compost independently. Also on the Double Tumbler is a compost tea collecting base which collects excess composting liquid for later use on plant root and soil. As with the majority of our tumblers, the Double Tumbler is manufactured using recycled Polyethylene in Lake City, Pennsylvania. This plastic is BPA free and FDA approved for contact with edibles. Setting up the composter is easy; Simply place the composter in a mostly sunny spot (partial shade in hotter climates) and you're done. The composter comes fully assembled. The Double Tumbler will take your composting to the next level.
