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.
Producing more with less is in our roots. Since we invented hydroponic stone wool growing in 1969 we have continuously evolved the Grodan approach to sustainable growing. Our growing media enables growers to provide their plants with water and fertilizer much more precisely and efficiently. By doing so, yield and quality can increase, while at the same time saving water and fertilizer and decreasing overall costs.
Today, our growers make use of a wide range of innovative products for the entire growing cycle, from the start of propagation till harvesting. At Grodan, we are driven to continue developing revolutionary products and technology to support Precision Growing for generations to come.
