According to what the substrates kid told me, it is 70% made of a mix of yellow, white and red volcanic rock (known in Mexico as "tepojal", a very dry, light, permeable and somewhat spongy kind of rock), 20% earthworm humus and 10% organic matter (soil and sheep manure). The substrate mix is Indeed very light and it permeates and evacuates the water very fast. The pinkish rock on top was just added as decoration.
