Worm culture/compost maker (Top Amersham HP6)

Mine is similar to this one. It has three boxes. You put vegetable/food waste/paper/cardboard/leaf mold into the top container and add the worms. They break down the waste and turn it into compost. When that box is full, you put it down at the bottom of the stack and start the next one. Each box is perforated so that the worms and liquid can escape. In the bottom box the liquid is stored. This can be diluted and used as a plant fertilizer. I haven't used it for some time but it's still good to go.
