| Abstract | ||||
| This research was done to gauge and control the hydroponic system's operational characteristics. Four different operating pressure levels of 0.50, 0.75, 1.00, and 1.25 bar and four different nutrient solution temperatures of 16, 22, 28 and 34 oC were tested, as well as the impacts on oxygen level, herb productivity, water productivity, and power consumption of peppermint seedlings that were. The findings demonstrated that the ideal production circumstances were peppermint age of 45 days, nutrient solution temperature of 28 °C, and operating pressure of 100 kPa. The findings also indicated that there were 102.06 leaves, a plant height of 21.73 cm, a stem diameter of 2.25 mm, and a total leaf weight of 5.7 g/plant. The maximum dissolved oxygen concentration was 6.92 mg/L. The greatest root length recorded for peppermint was 48 cm, operating at 100 kPa and a nutrient solution temperature of 22 °C (1bar). At a root zone temperature of 28°C, peppermint water productivity reached its greatest value of 0.099 kg/m3 and the maximum amount of essential oil was 2.73%. | ||||
