Soil (substrates) for greenhouses (protected crops)
Volcanic granules including Pumice and Lapilli replace perlite and expanded clay in the substrates of protected crops.
Unlike perlite and expanded clay, these materials have an internal microporousity that allow for adequate drainage, while at the same time improving air circulation at the root level.
This dramatically reduces the onset of diseases caused by excessive water and poor root oxygenation.
The presence of Zeolite improves the crop’s ability to retain nutrients and encourages rapid and lush development.
In short, it’s an energy shot for your crops made of peat substrates.
