About Product
Grodan Stone wool (rock wool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rock wool 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.

Benefits of Rock Wool
- Rock wool is extremely moisture retentive.
- Provides great aeration, allowing your plants’ root systems to obtain proper levels of oxygen.
- Rock wool is also a convenient choice for growers because it breaks apart so easily, you can adjust the sizes to meet your needs.
- Throughout the growing cycle, you can rest assured that your rock wool substrate won’t degrade and breakdown over time. It will be strong and continue to retain water properly.
