摘要：
The invention provides a multiple density growth substrate product (1) formed of a coherent matrix of man-made vitreous fibres (MMVF) bonded with binder, having an upper surface (2) provided with a recess (3) adapted to receive a seed or seedling and an opposite lower surface (4) on which the product rests when in use, the product being formed of at least two layers including an upper layer (5) positioned at the upper surface and having a first density and a lower layer (6) positioned at the opposite lower surface and having a second density, wherein the first density is less than the second density by at least 5 kg/m3 and wherein the loss on ignition (LOI) in the upper layer is at least 3.5 wt %. The invention also provides the use in methods for growing plants, especially pepper plants, of a mono density growth substrate product formed of a coherent matrix of man-made vitreous fibres (MMVF) bonded with binder, having an upper surface provided with a recess adapted to receive a seed or seedling wherein the density of the product is not more than 70 kg/m3 and the loss on ignition (LOI) is at least 3.5 wt %.
