Hydroponic method and system

摘要

A hydroponic pond is provided that has a depth in the approximate range from 24 inches to 36 inches. This depth of pond water provides a volume of water that increases thermal stability of the hydroponic pond. A nutritional formulation is developed in view of an analysis of a source water make-up for combination with the source water to achieve a desired chemical and nutritional mix. The nutritional formulation and the source water are then combined and placed within a hydroponic pond. A computational system is provided that monitors the state of a hydroponic environment and directs input modules as programmed and in order to sponsor plant growth, plant quality, and volume of plant yield.

1. A hydroponic system having a control program to monitor a state of a hydroponic grow environment and control multiple input modules so as to facilitate cultivation of plants, the system comprising:
a tank having a depth in a range from about 24 inches to about 36 inches, the tank being configured to hold a water volume that provides a water depth greater than 24 inches; a greenhouse encompassing the tank, the greenhouse adapted to impede ambient airflow to and from the tank; an oxygen sensor adapted to measure an oxygen concentration of the water volume; an oxygen dispensing tube disposed within the water volume; an oxygen source coupled with the oxygen dispensing tube and adapted to controllably deliver oxygen to the oxygen dispensing tube; a pH sensor adapted to measure a pH level of the water volume; an acid delivery module adapted to controllably release an acidic agent into the water volume; a salinity sensor adapted to measure a salinity of the water volume; a nutritional additive delivery module adapted to controllably release a nutritional additive into the water volume; and a controller operably coupled to the oxygen sensor, the oxygen source, the pH sensor, the acid delivery module, the salinity sensor, and the nutritional additive delivery module, wherein the controller is responsive to the control program to:
direct the oxygen source to deliver oxygen to the oxygen dispensing tube in response to receiving the measured oxygen concentration from the oxygen sensor and determining that the measured oxygen concentration is below a programmed oxygen concentration amount;direct the acid delivery module to release the acidic agent into the water volume in response to receiving the measured pH level from the pH sensor and determining that the measured pH level is above a programmed pH level; anddirect the nutritional additive delivery module to release the nutritional additive into the water volume in response to receiving the measured salinity from the salinity sensor and determining that the measured salinity is below a programmed salinity amount.
