Wormery?

I have a wormery but it's only for suitable sized worms used for fishing!  Its just a large plastic contaner which I put worms into so that when i go fishing I only have to tip it out, grab as many worms as I need then put the soil and the rest of the back in. To save it getting flooded I usually put a wooden board over it and mix a few half decayed cabbage leaves in with the compost to keep the remaining worms happy.

Not what you were meaning I know, but that's my take on it!

Not what I was meaning at all but made me laugh
