Pon

Pon is a mineral stone substrate potting mix/growing medium.  Consists of high-quality, mineral stones that are free from contamination and pollutants and has an ideal air / water ratio for plants (45% water/55% air)

Even after some time, the structurally stable plant substrate does not condense and it keeps its air-permeable structure. In addition, it can be used for years, without having to be replaced! 

Pon contains pumice, zeolite, lava rock, biochar, fluval stratum.
