• Grow-Cubes stack on top of each other leaving air space in between them this promotes root growth.

• Very easy to mix with any other potting mix.
• Special advantages are achieved by mixing Grow-Cubes in with clay pellets. The Grow-Cubes will help spread the water in the container as well has keeping a water buffer in between the watering.
