GRODAN ROCKWOOL GROWING MEDIA

GRODAN ROCKWOOL GROWING MEDIA

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 stone wool Granulate is bags with little flocks of 'angel hair'.
