### The Temperature and Humidity in the Greenhouse Using the Optimum Flow Rate of Water Misting  
With the experience of misting discharges of \"80 L/h\" and \"60 L/h\" and by modifying the direction of the nozzle by rotating sixty degrees uniformly in a clockwise direction, the use of misting discharge in this step was set as follows. From 7 a.m. to 8 a.m., the water discharge is \"50 L/h\"; 8 a.m. to 10 a.m. \"60 L/h\"; 10 a.m. to 11 a.m. \"100 L/h\"; 11 a.m. to 1 p.m. \"120 L/h\"; 1 p.m. to 2 p.m. \"80 L/h\"; and 2 p.m. to 3 p.m. \"60 L/h\". Furthermore, starting at 3 p.m., the misting system was turned off to maintain humidity not exceeding 85%, because the temperature does not exceed \"33 \({}^{\circ}\)C\". Table 8 and Figure 7, as well as Table 9 and Figure 8, show the temperature and humidity data in the greenhouse for the new misting discharge setting conditions. Data on its comparison to the previous test conditions are also shown. Setting the water discharge for misting that is adjusted to the needs of controlling temperature and humidity has resulted in a more efficient use of the total volume of water. The use of water for misting in a day is 652.9 litres or 150.9 litres more efficient than misting systems with a constant flow rate of \"80 L/h\". \begin{table}

Table 8: Temperature in the greenhouse using the optimum flow rate of water misting. Figure 7 shows that the misting system can reduce the temperature more effectively than using a water flow rate of \"80 L/h\" and \"60 L/h\". From 7 a.m. to 10 a.m., the temperature is already at an ideal condition that is not higher than \"33 \({}^{\circ}\)C\". Starting at 10 a.m., the water flow is increased to \"100 L/h\" so that at 11 a.m., the temperature decreases. This is undertaken to maintain temperature spikes during the day, especially from 11 a.m. to 2 p.m., where, in the \"80 L/h\" and \"60 L/h\" tests at that time, the temperature consistently exceeded \"33 \({}^{\circ}\)C\". At 11 a.m., the water flow was increased again to \"120 L/h\" because, during the day, the sun's radiation increases the temperature in the greenhouse [14]. At 1 p.m., the water flow is reduced to \"80 L/h\"; from 2 p.m. to 3 p.m., the water flow was \"60 L/h\". By optimising the misting system, the temperature in the
