    Abstract: A man-made vitreous fibre (MMVF) plant growth substrate is provided. The substrate has properties including a volume of 3 to 20 litres, two layers of differing density, and the use of a hydrophilic binding system. This is found to provide a substrate which allows excellent control of the water and/or nutrient contents within the substrate when used for plant growth.

    Abstract: A method and an apparatus for horizontally splitting a mineral wool web includes a conveyor having a first direction of travel adapted for receiving and advancing a cured mineral wool web in said first direction. At least one dividing device is provided for longitudinally dividing the cured mineral wool web into at least two sub-webs as said cured mineral wool web is advanced passed said at least one dividing device. At least one lifting mechanism is provided downstream of the dividing device so that a section of the conveyor is adapted for lifting a sub-web. At least one horizontal cutting device is provided for horizontally cutting the sub-web whilst lifted in said conveyor section.
