- Bottom Tier (Leachate Collection):
- This tier does not get bedding, food scraps, or worms intentionally.
- Its sole purpose is to collect leachate ("worm tea") from the upper composting trays.
- Do not add newspaper, cardboard, or soil here.
- Optional: Add twigs, mesh, or screen to help any wandering worms climb back up.
- Ensure the spigot is open occasionally or place a container underneath to collect liquid.
