Grodan®

Precision Stone Wool. Sustainable Roots.

Grodan® is the original innovator in stone wool substrates, dating back to 1969 when they pioneered this clean, sterile growing medium to replace soil disinfection methods. As a key member of the Rockwool Group, Grodan® combines decades of innovation with sustainable design, helping growers in over 70 countries optimise water use, reduce chemical inputs, and improve yields.

Their range, from propagation plugs and starter cubes to grow slabs and granules, is crafted from melted basalt and limestone spun into uniform wool, offering excellent aeration, moisture retention, and root-zone control. Clean and inert, Grodan® substrates enable trusted precision growing from seed to harvest, and can be fully recycled post-use.

At Hydro Oasis, we choose Grodan® for its professional-grade consistency, eco-conscious design, and unrivalled support for precision horticulture. Whether you're launching seedlings or running a large-scale greenhouse, Grodan® ensures you’re growing smarter, from the roots up.
