Soilsaver Base: A base (bottom) is not necessary. Most compost bins are open at the bottom for better air circulation, and to allow good bacteria, worms and bugs to come into your bin, speeding up the composting process. A base could help with any major rodent issues at your location. Make sure you always burry any food scraps under outdoor green waste to avoid these issues. Click here to purchase a base (bottom) for the Soilsaver Composting Bin.
