摘要：
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.
