I build wooden vermicomposting bins (worm bins) because I wanted to keep the worms in my kitchen, but was not a fan of the usual Tupperware bin look. I have sense made some improvements. You will note the lack of vents. There were some but not enough. You definitely want to give your worms lots of air.
I have made some improvements, added some more vents and a screen inside. I also put it on casters so I can move it around the basement without having to lift it every time.
This is one I modelled on the original vermicomposting bin design, I used some old cedar tongue and grove boards. They were washed out during the June 2013 flood and were destined for the landfill.
The inside is lined with a poly film to protect both the wood from moisture but also, I have heard the worms don’t like cedar, so its a double purpose I guess.
The hinges were off an old door I took out years ago and I have hung onto for some reason. It took about an hour to clean the paint and corrosion of them, but I finally found a use. The fun and beautiful part of building with recycled material.
The construction allows for it to be used as a bench. That is why there is no vent in the top. The over all weight is a two person lift.
