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.
