The plant granulate Bio Granuplant Indoor is a sustainable alternative to conventional clay granulate. It is made from 100% natural pumice stone and provides optimal growth conditions for ornamental plants. With its high water retention capacity and simplified nutrient uptake, it supports healthy plant growth. Unlike expanded clay, the granulate does not need to be washed before use, allowing the plant to be planted directly. The granulate can be used both as a planting substrate for plants with root balls or from hydroponics, as well as for covering the top layer of soil in the planting container.
