The specific physical characteristics of the substrates, including high porosity and water retention, are calibrated by varying the grain size of the pumice and inert volcanic materials, as well as the peats used, thus reproducing the optimum condition for roots and growth, depending on the plant type and the size of the
growing vessel.
