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 fro

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 plant growth system is provided, which includes: one or more plant growth substrates comprising an MMVF slab and a single MMVF block; one or more detectors arranged to monitor at least one of the water and nutrient levels of at least one of the plant growth substrates; at least one irrigation device arranged to supply water and nutrients to the plant growth substrates; and control mechanism connected to said detectors and said at least one irrigation device. The supply of water and nutrients by the at least one irrigation device is controlled by the control mechanism in dependence on the monitored water and/or nutrient levels. In this manner, the water and nutrient levels of the substrates can be accurately controlled.

Abstract: A device (10) and method are provided for measuring the plant growth conditions within a substrate. A first and a second linear arrays of probes (16, 18) are used, allowing multiple measurements of properties of the substrate. Using multiple measurements at different levels in the substrate and then combining these multiple measurements, allows plant growth conditions to be accurately derived.
