In order to accurately determine the amount of nutrients required by a plant, the amount of nutrients distributed in the irrigation water that were not taken up by the plant needed to be determined. To measure the nutrients another container, a collection container for receiving excess water from the plant container, was placed under a plant container, as can be seen in FIG. 7, part 35. The collection container, FIG. 1, part 5 under the plant container, FIG. 7, part 36 from the plant which allowed sensor, FIG. 7, part 37, to be placed in the collected water to measure the chemical content of the excess water. These sensors included 31 Series or 35 Series—sealed polycarbonate pH electrode, 02 Series—epoxy body conductivity electrode, or 35 Series—ion selective electrodes (Analytical Sensors and Instruments, LTD) which measure levels of ammonium, calcium, cupric, nitrate, nitrite, potassium, sulphide. Alternatively, the chemical content could also be determined through standard laboratory test procedures and entered into a computer manually.
