Lechuza-Pon is the perfect alternative in places where conventional soil cannot or should not be used. LECHUZA-PON has an ideal air / water ratio for plants (45% water/55% air). It also reduces a plant's vulnerability to diseases. Even after years, this structurally-stable plant substrate does not condense and keeps its air-permeable structure. LECHUZA-PON can be used for years without needing to be replaced! 

The purely mineral-based plant substrate blocks fungi that can attack the roots. Therefore, PON is suited for people who suffer from allergies. It can also prevent bugs such as gnats, since they typically only nest in soil.
