Abstract:
1. A method of monitoring one or more growing plants comprising (i) providing at least one plant in a growth substrate which contains water, (ii) providing a monitoring system comprising (a) a first data storage means containing stored data on the optimum water oxygen levels for at least one, of growth conditions and (b) a first calculating means for comparing input actual growth conditions and actual water oxygen levels with the stored data and producing a first output result and (c) input means for supplying to the monitoring system actual growth conditions and actual water oxygen levels, the process comprising (iii) measuring the actual water oxygen level in the region around the roots of the at least one plant, (iv) providing the actual water oxygen level to the first calculating means, (v) determining at least one growth condition and supplying the growth condition to the first calculating means, whereby (vi) the first calculating means compares the actual water oxygen level and the at least one growth condition with the stored data and provides the first output result.
