Abstract: A system and related method for monitoring plant growth conditions is provided, comprising a plurality of detectors (7) and central detector data processing means (1103); each detector (7) being arranged to measure properties indicative of a temperature, a water content, and a nutrient content, of a plant growth substrate; each detector (7) being further arranged to transmit the measured property or properties over a communications link to the central detector data processing means (1103); the central detector data processing means (1103) being arranged to store predefined irrigation data, defining a relationship between plural values for temperature, water content, pH level and/or nutrient content of the plant growth substrate; and plural desired irrigation output values; process the measured properties from each detector (7) to determine calculated properties of the substrate; and provide an output indicative of a desired irrigation input for the growth substrate, based upon measured properties received from the detectors (7) and the predefined irrigation data. A portable detector communications device (1105) for communicating configuration data relating to the detectors (7) may be included in the system.
