GROW!T Commercial Coco is our 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.
GROW!T Commercial Coco is the most versatile size in the lineup. Growers can use the blocks for vegetative growth for plants going into larger containers, or they can be used for flowering by stacking the 4x4x3 on top of this 6x6x4. Another approach is to veg and bloom plants only in this block, using modern automated fertigation methods. RapidRIZE blocks start off compressed for easy shipping and storage, but they expand fully in approximately 1 minute after saturation. All RapidRIZE blocks feature a wide, low-profile shape, to match the specific rooting pattern of your favorite herbaceous annual plants.
