Mineral wool is a generic name for fiber materials that are formed by spinning or drawing molten minerals. The nomenclature of these wool products is simply the parent/raw material name in prefix to wool. Wool from glass is glass wool, wool from rock is stone wool and so on.   Many people incorrectly believe that ROCKWOOL is a synonym for mineral wool.  However, ROCKWOOL® is a registered trademark by the Danish company Rockwool International A/S.   SA Horticulture does not sell ROCKWOOL, but other brands of stone wool.  Mineral wool products can be engineered to hold large quantities of water and air that aid root growth and nutrient uptake in hydroponics; their fibrous nature also provides a good mechanical structure to hold the plant stable. The naturally high pH of mineral wool makes them initially unsuitable to plant growth and requires “conditioning” to produce a wool with an appropriate, stable pH.
