BLACKSTONEPON surpasses traditional potting soil with its pure mineral plant substrate, featuring natural charcoal and black lava that give it an exceptional dark colour. It serves as the ideal alternative to conventional potting soil, being structurally stable and supporting root aeration while optimally regulating water supply. Therefore, it is in no way inferior to LECHUZA's conventional plant substrates, as pumice, lava, and zeolite ensure high drainage ability and water storage, reliably supplying plants with sufficient water. The included charcoal stimulates root growth. As BLACKSTONEPON is pre-fertilised, plants are provided with nutrients for 6-8 months. For the love of nature, the substrate is peat-free. It can be used for all indoor plants, either for complete planting or as a decorative.
