摘要：
A method of growing a fruit or vegetable crop comprises: positioning a plant in the form of a seed or a seedling or a cutting of the crop in a first coherent mineral wool growth substrate having a volume not more than 150 cm3, allowing the plant to root and grow for at least 2 days and not more than 30 days, then transferring the plant within the first coherent mineral wool growth substrate so that the first coherent mineral wool growth substrate is in contact with a second coherent mineral wool growth substrate having volume 60 to 1500 cm3, and allowing the plant to grow for a further 2 to 5 weeks, transferring the plant within the second coherent mineral wool growth substrate so that the second coherent mineral wool growth substrate is in contact with a third coherent mineral wool growth substrate having volume of from 700 to 45 000 cm3, and allowing the plant to grow for a further 1 to 7 weeks before any further transfer is effected.
