Plant growth control system

Filed:2019-09-27Pub:2024-06-18
Applicant:ROCKWOOL International A/S

A system for controlling plant growth conditions in hydroponic growing systems, the system for controlling plant growth conditions comprising: at least one detector for measuring at least one property of a plant growth substrate or environmental condition; first and second data processing means; data storage means and the or each detector being arranged to measure a property or properties of a plant growth substrate or environmental condition 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 being arranged to: hold in a memory predefined growth data including irrigation data, environmental data, plant data, harvest data, crop data and/or climate data defining a relationship between: plural values for one or more of temperature, pH level, water content, nutrient content, oxygen content of the substrate, air temperature, humidity and light level, climate conditions, plant parameters, harvest and crop conditions; and plural desired irrigation parameters and environmental parameters; process measured properties received from each detector to obtain processed properties of the substrate; provide an output indicative of a desired growth input for the growth substrate, based upon the processed properties and the predefined growth data; and send processed data to the data storage means, the data storage means arranged to store the sent data as logged data; the second data processing means being arranged to: receive data from the data storage means; 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 a message condition input for outputting a message based on said difference; and output a message when said difference meets the message condition.
