The Compost Wizard Duel Senior Starter kit is a 12-foot composter that allows the user to work two batches of compost at one time. Each chamber can hold approximately 40 gallons and are separated so they can compost on their own. Included in the kit is a coca fiber brick, accelerant, and thermometer. The Cocoa fiber brick aides the bacteria that does a majority of the composting. The coco fiber (coconut coir) is the part of the coconut that is usually thrown away during the harvesting process until now! It works as a great peat moss replacement. The coco coir breaks down slowly, therefore it will not need to be replaced for several months. The accelerant included can treat up to 12 cubic feet of compost each. To apply to your compost, just add one bag of the accelerant to one gallon of water and then mix. Be careful not to add too much at one time to your compost, you may flood or over moisturize it. Bacteria feed on this 100% natural enzymes, and makes the composting process up to three times faster. The Compost Wizard Thermometer makes keeping your compost at the correct temperature a breeze. At 110 to 160 degrees Fahrenheit (44-71 degrees Celsius) the decomposition is at its peak. With the Compost Wizard Thermometer, you will be able to determine if your pile is too cool and if more materials need to be added, or if it is not receiving enough air or moisture. If your pile is too hot, it may need extra turning or water to help cool it down. With the large dial and bright red dial that gives measurements in both Fahrenheit and Celsius, you will be able to accurately determine the temperature of your pile. The stainless steel thermometer will not corrode and will hold up against use. Whether it’s used in a compost bin or a pile, the Compost Wizard Thermometer will give you an accurate reading and your compost will be done in no time. The Compost Wizard Dueling Tumbler Starter Kit is made in the USA, BPA free, and FDA approved. It is black in color, which allows the composter to absorb heat that aids in the composting process. Once you have your Compost Wizard Dueling Tumbler Starter Kit, all you have to is pick a sunny spot in your yard and place it there. No assembly required.
