2. Worms used in vermi-composting are often species like Eisenia fetida (red wigglers).
3. A well-constructed pit provides a suitable environment for worms and ensures proper composting.
4. Adding straw or dried grass helps with aeration and provides an initial substrate for the worms.
5. Earthworms break down organic matter and turn it into compost.
6. Regular watering is necessary to maintain optimal moisture for the worms.
