This substrate can also be used as a carbon-rich addition every time you add organic waste. It replaces cardboard or shredded paper: for every volume of scraps you add, simply add the same volume of substrate to keep your worm bin well balanced.

Thanks to its specific composition, it helps produce high-quality finished vermicompost that is lighter and airier than what you get with conventional carbon-rich materials.

This supplemental substrate is a great ally for efficient, stable, and sustainable composting, and it keeps your worms comfortable and active.
