Pozzolana is a natural rock with a great capacity for absorbing water, which makes it an excellent substrate conditioner. Its high water retention capacity means that this material can be used as a excellent addition to gardens, especially those with trees or plants.

Red pozzolana is characterized by having been formed after a relatively rapid solidification process coupled with to a strong degassing, this causes the rock to present a glassy shine and irregular shapes with numerous vacuoles, resulting from the escape of volcanic gases through it.

An inert and aerated substrate is obtained that is very suitable for hydroponic crops.

For the rest of the crops, the addition of pozzolan rock is recommended in order to improve the chosen substrate. Of In this way, the capacity of the substrates to retain water and nutrients is increased; sponginess is increased and aeration of the substrate, with which the roots develop better.

Being an inert mineral additive, it has the advantage of not generating bacterial life that modifies the availability of nutrients due to variations in the pH of the substrate.
