Worm Grotto™

093The patent-pending engineering that goes into the Worm Grotto™ has been years in the making.  From humble beginnings in a plastic tub in my garage, I’ve experimented with worm composters, raised worm beds and finally landed on the Worm Grotto™ composting system.  The compartmental design allows the worms to travel between the bins contained in the system. The worms are able to choose where they feel most comfortable, which is essential in extreme temperatures. The design also allows for maximum production on a rotating basis.

Due to high temperatures, we are only able to ship worms October through April. Summer worm orders may be picked up upon request.
