摘要： A man-made vitreous fibre (MMVF) plant growth substrate is provided together with an irrigation strategy for providing water to the substrate. The substrate comprises a slab having a volume of 3 to 20 litres on which a single block containing one or more plants is disposed. In the context of this substrate, it is found that an irrigation strategy can be used which comprises a first period during which the desired water content in the slab is reduced to a minimum level before increasing and a second period during which the desired water content is maintained at a substantially constant level, wherein the difference between the minimum level and the constant level expressed as a percentage of the water content required to saturate the plant growth substrate is less than or equal to 25%. This provides excellent control over the balance between vegetative and generative growth in the plant.

摘要： A method 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 or on a first coherent mineral wool growth substrate having a volume not more than 150cm 3 , allowing the plant to root and grow for at least 8 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 110 to 1500cm 3 , 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 cm 3 , and allowing the plant to grow for a further 1 to 5 weeks before any further transfer is effected.

摘要： A plant growth system is provided, which comprises: one or more plant growth substrates (1); one or more detectors (7) arranged to monitor nutrient levels of at least one of the plant growth substrates; at least one irrigation device (6) arranged to supply water to the plant growth substrates; and control means (9) connected to said detectors and said at least one irrigation device. The supply of water by the at least one irrigation device is controlled by the control means in dependence on the monitored nutrient levels. In this manner, the water and nutrient levels of the substrates can be accurately controlled.
