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