Abstract: 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.

Abstract: A system (10,11) for controlling plant growth conditions in hydroponic growing systems, the system for controlling plant growth conditions comprising: at least one detector (7,1101) for measuring at least one property of a plant growth substrate; first (9,1103) and second (9,12, 1107) data processing means; data storage means (1120); and the or each detector (7,1101) being arranged to measure a property or properties of a plant growth substrate and to transmit a detector identifier and the measured property or properties over a communications link to the first data processing means; the first data processing means (9,1103) being arranged to: hold in a memory predefined irrigation data defining a relationship between: plural values for one or more of temperature, pH level, water content, nutrient content, oxygen content, and plant parameters of the substrate; and plural desired irrigation parameters; process measured properties received from each detector to obtain processed properties of the substrate; provide an output indicative of a desired irrigation input for the growth substrate, based upon the processed properties and the predefined irrigation data; and send processed data to the data storage means (1120), the data storage means arranged to store the sent data as logged data; the second data processing means (9, 12, 1107) being arranged to: receive data from the data storage means (1120); calculate predicted properties of the substrate based on the logged data; determine a difference between the processed properties of the substrate and the predicted properties of the substrate; receive an alert condition input for outputting an alert based on said difference; and output an alert when said difference meets the alert condition.
