GROW!T Commercial Coco is Hydrofarm’s premium growing medium brand, designed specifically for the professional grower. The entire line of GROW!T Commercial Coco is lab tested lab tested for heavy metals, so your plants can grow in the purest coco available.  This high-quality coir is processed indoors to eliminate debris and pollutants.  Repeated washes and buffering are applied to achieve extra-low ppm/EC levels, so you can apply nutrients and supplements the same day you plant.
