Grodan Grow-Cubes – Grow-Cubes - 2 cu. ft. - Case of 3 Bags

Grodan Grow-Cubes Grow-Cubes are small loose 1/2 in cubes of stonewool. Advantages are better aeration, maximum drainage so that you can hardly ever overwater your plant, easy mixing with other loose media (such as expanded clay rocks or coconut fiber), lightweight and much cleaner than peat-based media. The properties of Grow-Cubes™ make it like a 50/50 mix of absorbent to repellent stonewool. Grow-Cubes stack on top of each other leaving air space in between them this promotes root growth. Each cube has four surfaces from which excess water can drain. This way, even if you water a lot, the Grow-Cubes will not get waterlogged. Very easy to mix with any other potting mix. Special advantages are achieved by mixing Grow-Cubes in with clay pellets. The Grow-Cubes will help spread the water in the container as well as keeping a water buffer in between the watering. We have plenty of clay pellet options in our Clay Pebbles & Growstones category What is Rockwool? Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums. Comes in: Case of 3 bags Case of 6 bags 1 Box (Loose box)
