I had a empty cinder block bed that I wanted to experiment in by doing a wedge type system. Usually wedge systems are on a larger scale but I got the idea of utilizing what I already have from a conversation I had with another female small business worm farmer at the Vermiculture Conference in Raleigh NC this year. (Thanks, Mel)
After combining all my bedding materials and food inside the bed, I took half of an established bin of red wigglers and mixed it all together.
If you notice I left some room at the top so I could add a thick layer of leaves for winter insulation.
With a wedge you need three supporting sides and a open end. The open end is where you place fresh food and bedding and the worms will migrate to the fresh food leaving castings behind.
When you get to the end you harvest the finished castings up to that end spot and then reverse back to the other end.
Absolutely genius idea!! At least I hope it works out that way. I will update as time goes by.
Happy Worm Farming all !
