The Dueling Tumbler already takes your composting to the next level but you can go even further with the included accessories. The Coco Fiber brick is perfect for those with a need to compost but have little access to carbon-rich ingredients such as urbanites. More than a simple substitute, the Coco Fiber is a natural biproduct of the coconut harvesting process and is a great peat moss replacements as well. In compost, the fibers act like a sponge and create micro pockets of air and moisture that become production centers for the thermophilic bacteria that perform the heaviest composting action. Combined with the included compost accelerant and you can expect to get great compost in no time. The included accelerator pouch includes 2-bags that can be mixed with water and added to the batch. Each bag can treat 12 cu. ft. of compost. And you can track your compost batch's status with the large, specially designed compost thermometer. The large 19 in. probe can nestle deep into the center of your batches to get accurate temperature readings in both Celsius and Fahrenheit, with a range from freezing to boiling. Knowing how hot your compost is can greatly help with troubleshooting or to determine if moisture should be added, contents turned or a change up in ingredients should take place. No matter what your level of experience, the Compost Wizard Dueling Tumbler Starter Kit will give you all the tools you need to be a composting master. Color: Black. Material: Polyethylene.
