Water-Storing Soil Cubes with Kitchen Sponges
Materials
Heavy duty green kitchen sponges (5 pieces)
Perlite (1 cup)
Potting soil (1 gallon)
Sharp scissors or a utility knife
Blender
Medium-sized mixing bowl
Directions
Start by cutting the heavy duty green kitchen sponges into small pieces, roughly 1-inch cubes, using sharp scissors or a utility knife.
Place the sponge pieces into the blender. Blend in short pulses until the pieces are further reduced to a fibrous, crumb-like texture.
Transfer the blended sponge material into a medium-sized mixing bowl.
Add 1 cup of perlite to the bowl with the sponge material. Mix thoroughly to ensure even distribution.
Gradually incorporate 1 gallon of potting soil into the mixture, stirring continuously until all components are evenly combined.
Form the mixture into small, compact cubes by pressing handfuls of the mixture together. Ensure each cube is dense enough to hold its shape.
