Similar in design to the popular Worm Factory® 4-Tray Composter (CAD002), The Worm Factory® 360 Recycled Plastic Worm Composter - Black features a thicker, sturdier design with an improved base and lid. This composter can hold up to 8 trays instead of 7, and it includes a handy compost accessory kit, featuring a coir brick, hand rake, scraper, and thermometer, which make maintaining your system cleaner and easier. It even comes with an instruction video that's great for beginners. The Worm Factory® 360 composter also features new Thermo Siphon Airflow design, which allows air to enter on all four sides of the base, exposing the bottom tray to an endless supply of fresh air without allowing light inside. The lids is also vented on all four sides, which allows the heat and gases generated during composting to continually escape through the top.
