Claim 11:
12. The method of claim 11, further comprising:
connecting a plurality of sensors to each zone controller, wherein the plurality of sensors includes at least a nutrient temperature sensor, an ultrasonic level sensor configured to measure a nutrient level in the hydroponic plant growing zone, and an atmospheric temperature and humidity sensor;
generating, by each of the plurality of sensors, sensor signals; and
publishing the first sensor signals to the zone controller through the data distribution service middleware;
connecting a first plurality of actuators to each zone controller, wherein the plurality of actuators includes at least a ventilation fan configured to generate air flow in the hydroponic plant growing zone and at least one submersible pump configured to pump the nutrient solution through a fluid transfer system;
generating, by the zone controller, a set of drive signals configure to control each actuator;
publishing, by the zone controller, the set of drive signals to the data distribution service middleware; and
receiving, by each of the plurality of actuators, the set of drive signals from the zone controller from the zone controller through the data distribution service middleware.
