The Good Ideas Compost Wizard Standing Bin is your home composting solution. Made of light durable polyethylene, this unit is easy to set up yet durable enough to weather mother nature's abuse. The ribbed design reinforces the structure while helping with aeration and makes the whole unit more attractive. Aeration holes are located around the outside and help to speed decomposition but are too small for rodents and other animals to get through. Both the top lid and lower access hatch are large with easy-to-grip hand holds for convenient access. Setup takes about 5 minutes and is as simple as using just a few fasteners to secure the top to the two bottom interlocking pieces. Customize which side the bottom hatch is on for convenient access. The black color absorbs the sun's light and heat to speed decomposition. Operation is straight forward: keep adding material as you wish or until the bin is full. Then let gravity do most of the work. Aerate materials at intervals (a few times a week depending on your location and conditions) and monitor temperatures to ensure a quick turn over.
