Sustraberry Blueberry Premium is a substrate based on a mixture of coarse blonde peat, with Cocopeat Coarse® coconut fibre and perlite. It is a long-lasting growing media, since the coco peat degrades less than peat, providing physical stability. In addition, the coir fiber avoids compaction and, therefore, facilitates proper drainage. The proportion of special blonde SOD peat provides nutrients to the substrate, so that the crop can establish its roots properly. The perlite also contributes to the durability and provides the growth medium with the necessary aeration.
This substrate is, therefore, perfect for plants that, like the blueberry plant, require an acidic pH soil level. The optimum range is between 4.5 and 5.5.
