HESI PowerZyme is a cellulase-extract from the trichoderma fungus (a so-called ascomycete, or also ascomycota), which decomposes the cellulose of dead plants into recoverable dextrose. This dextrose serves as nutrition for roots and for soil flora. HESI PowerZyme provides an oxygen-rich root environment by avoiding decay and improves the biological balance. HESI PowerZyme interacts in the soil and root flora between the plants, the substrate and the microorganisms found there. HESI PowerZyme is suitable for all types of cultures.
