GROW!T® Commercial Coco Bale 90/10 Mix is a premium growing medium designed specifically for professional growers, made from a blend of 90% coir and 10% pith to support consistent plant development. This high-quality coco coir is processed indoors to eliminate debris and pollutants, then repeatedly washed and buffered to achieve extra-low ppm/EC levels, allowing nutrients and supplements to be applied the same day as planting. Lab tested for heavy metals, it provides a clean and stable growing environment for hydroponic and soilless systems.
