About Us

Green Diamond Stonewool was created by a small group of hydroponic growers who were passionate about maximizing the capabilities of Rockwool. With drive, diligent research, and a commitment to excellence, Green Diamond Stonewool was established. Our goal is to offer affordable, cutting-edge Rockwool cubes and other products to the hydroponic industry.

Green Diamond Stonewool Rockwool products are designed to create healthier root systems and larger yields. Our rockwool cubes have the perfect amount of air pockets and encourage vigorous, multidirectional root growth throughout.

What Is Rockwool?

The use of Green Diamond Stonewool substrate offers many advantages. The controlled manufacturing process consistently delivers a high-quality Rockwool for growing. The sterile production under extreme temperatures ensures that the product is clean and sterile. Its unique hydrophilic fibre also makes the cultivation on stonewool substrate very easy to control. The grower can administer the amount of water and nutrients the crops need in a very directed and controlled manner, to achieve optimal growing results.
