Here we will discuss how to compost as a foodstock for our wigglers. We will also discuss the differences and benefits of compost, vermicompost and earthworm castings.
This picture is of one of my horizontal flow through bins. The center portion is divided by a chicken wire screen and frame. The bin measures 2’x2’x4′ and will hold a little over 100 gallons of material. The left side of the bin had been recently harvested for worms and vermicompost. The right side of the bin is material that has finally cooled down from the heat caused by thermophilic composting. Since it was cool any leftover worms were added to this side and the process of thermophilic composting was repeated on the left side.
The process continues on in this circle. Organic coffee grounds, sawdust, horse manure, grass clippings, etc are the typical inputs for the composting side. A 30:1 Carbon to Nitrogen ratio is ideal. I will post a chart and talk about this further when I get more time.
