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 an organic binder selected from formaldehyde free binders. 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 plant growth system is provided in which an irrigation device provides water and/or nutrients to a plant growth substrate. The plant growth substrate comprises an MMVF slab and a single MMVF block on a first surface of the MMVF slab. The MMVF slab comprises a drain hole which is disposed at one end of the surface, and the irrigation device provides water and/or nutrients to the substrate at a position more than 50% of the length of the slab away from the drain hole. This improves the control of water an nutrients in the slab as a whole.

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. The height of the two layers lie in the ranges of 25 mm to 50 mm and 50 mm to 100 mm 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.
