Oops, Christmas refers to this post, not the last. Being crafty in my composting marriedness, I inveigled my poor spouse to procure the bin. I sent him pictures from Amazon and my favorite composters site. He ignored me and purchased the Can-O-Worms.

The Can-O- Worms is considered to the most popular home-vermicomposting system in the US. You get a legged base with spigot, three trays, and a top. The spigot is for releasing the liquid (called leachate) that may drain from the composted organic waste -- this makes prime fertilizer for indoor plants. The Can-O-Worms is made with recycled plastic and comes packaged in cardboard that you then use in the Can -- nothing is wasted.

You can vermicompost in just about any plastic or wood container that allows aeration. Some people get Rubbermaid bins and drill holes in appropriate places -- this would be horizontal vermicomposting, since they'd be using the entire bin at the same time. With horizontal vermicomposting, there's time and mess with harvesting out the finished product, separating the worms, etc.

The Can-o-Worms is a vertical unit that supposedly makes harvesting and separating easier. Ostensibly, you start with the worms and the food in the bottom bin until it's full, then add food to the next up bin and the worms migrate up once the food is fully digested in the lower bin.
