Stone wool, also known as mineral wool or rock wool, is a soilless growing media ideal for indoor cultivation of all plants—from cannabis to vegetables and floriculture.
Since 1969, Grodan® has been the global leader in providing innovative and sustainable stone wool solutions, advancing indoor gardening technology. Our Precision Growing principles, combined with technical crop advice and advanced tools like rootzone sensors, help growers achieve rapid root development, consistent production, and maximum yields with minimal resource inputs.
Stone wool is the preferred substrate due to its compatibility with various plant production systems, irrigation methods, lighting types, nutrient delivery systems, and other precision growing techniques.
The standardized size and shape of each Grodan® stone wool product enable cultivators to create a graduated system that supports plants from seedlings through to harvest.
And after the growing cycle is complete, stone wool is recyclable in more and more places around the world.
