Applications: Green roof and light intensive gardens. pH satisfies a wide range of garden species, including moderately acidophilic plants.

TerraMediterranea TMI mineral substrate is designed with the main objective of maximizing fertility and supporting demanding and diverse vegetation. The organic matter supply is higher than other Harpo substrates, the pH is sub-acidic, and the C/N ratio low. It exhibits excellent performance in water management, both in maximizing retention and deferring runoff.
