What is Grodan Stonewool?
Grodan stonewool was developed in Denmark in the early 1970's. The process makes excellent use of nature resources; We can produce 37 cu.ft. of wool from 1 cu. ft. of rocks.
It is back to Nature. The raw material is basalt rocks and chalk. These are melted at 1600 C°. The lava is blown into a spinning chamber, which pulls the lava into fibers, much like ?cotton candy'. When Mother nature makes this wool we call it ?angel hair'. If you have ever visited a volcano, you may have seen the fluffy angel hair flying around.
We pack the fibers together into a mat and cut Grodan slabs & cubes from it. The stonewool granulate is bags with little flocks of 'angel hair'.

Stone wool
Grodan stonewool is the main reason that most of the worlds greenhouse vegetables are now grown hydroponically.
At full saturation, Grodan holds 80-90% of its volume in water. It is wrapped in biodegradable plastic and the stonewool can be re-used in your garden to improve the aeration and water holding capacity.
Grodan stonewool went into space on Challenger in 1986 and is still being used in NASA's testing with hydroponics.
You will find Grodan stonewool in some garden centres and in virtually all hydroponics shops in North America.
Growcubes
Grodan® Growcubes are small 1/4" cubes of stonewool (rockwool). There are several advantages;
- When the cubes are wetted, they stack on top of each other leaving airspace in between the cubes.
- Each cube has four surfaces from which excess water can drain. This way the Growcubes will not get water logged.
- Less algie growth on the top than with the smooth surface Gro-blocks.
- The Growcubes are the driest of our products with properties of a 50% water/50% air mix.
- Very easy to mix with any other potting mix.
- Light weight.
Ways to recycle
Grodan produces a huge amount of Grodan from recycled Grodan.
In this day and age we are all much more aware of the importance of protecting our environment. What many do not know is that growing hydroponically is far better for the environment than traditional growing methods; You have the choice of recycling the water you drain, instead of leaching fertilizer into the ground.
Starting with a pathogen-free product, you have less disease problems and thus use far less pesticides (90% less).
