GROW!T Commercial Coco — RapidRIZE Block 4"x4"x3", Case of 120

GROW!T Commercial Coco is Hydrofarm’s premium professional-grade growing medium, engineered for commercial growers who demand consistency, purity, and performance. Every batch is lab tested for heavy metals and processed indoors to eliminate debris and pollutants. Repeated washing and buffering achieve extra-low ppm/EC levels — so you can apply nutrients and supplements the same day you plant.

RapidRIZE Block — Built for the Vegetative Stage

The 4"x4"x3" RapidRIZE block is designed specifically for the vegetative stage. Its compact footprint fits standard grow trays to maximize plant counts in early growth, while the wide, low-profile shape matches the natural rooting pattern of herbaceous annual plants. Blocks ship compressed for efficient storage and expand fully in approximately 1 minute after saturation.
