Description<\/h2>\n

RapidRIZE, The worlds fastest expanding coco blocks.<\/h2>\n

Grotek\u2019s high quality coco coir products are designed to provide the best coco substrate for optimal growth and high yields.<\/p>\n

Grotek’s Commercial Coco is a premium growing medium brand, designed specifically for the professional grower. The entire line of Grotek Commercial Coco is lab tested for heavy metals, so your plants can grow in the purest coco available.\u00a0 This high-quality coir is processed indoors to eliminate debris and pollutants.\u00a0 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.<\/p>\n

The 15cm x15cmx\u00a0 block from Grotek Commercial Coco is the most versatile size in the lineup.\u00a0 Growers can use the blocks for vegetative growth for plants going into larger containers.\u00a0 Another approach is to veg and bloom plants only in this 15cms x15cms block, using modern automated fertigation methods.\u00a0 RapidRIZE blocks start off compressed for easy shipping and storage, but they expand fully in approximately 1 minute after saturation.\u00a0 All RapidRIZE blocks feature a wide, low-profile shape, to match the specific rooting pattern of your favorite herbaceous annual plants.<\/p>\n
