Abstract

------29 / 08 / 2568------(OCR) The OCR 10KL hydroponic cannabis growing system consists of a large water tank (1) connected to a nutrient mixing tank (2) to prepare the nutrient solution. A current sensor (3) and a pH sensor (7) are installed inside the tank, controlled by a current regulator (4) and a pH regulator (8) for fertilizer absorption and adjustment. The hydroponic system's operation begins with a timer for water delivery and return. An inlet pump (11) sends water from the large water tank (1) to the nutrient mixing tank (2) and the growing tank (16). Simultaneously, nutrient solution is delivered to 80% of the growing tank (16), taking 12 minutes to deliver the solution. Afterward, the roots are allowed to absorb nutrients for 18 minutes before an outlet pump (13) draws the solution back into the large water tank (1) in 15 minutes, allowing the roots to receive oxygen for 45 minutes. This process is repeated for 90 minutes per cycle, for a total of 16 cycles per day. ------------ ------06 / 12 / 2567------(OCR) The OCR 10KL hydroponic cannabis growing system consists of a large water tank (1) connected to a nutrient mixing tank (2) to prepare the nutrient solution.

This mixing tank is designed to mix the fertilizer and water delivered from the large water tank. The fertilizer mixed with water is called a nutrient solution. Inside the fertilizer mixing tank, an electrical conductivity probe (EC probe) is installed to monitor the electrical conductivity (EC) of the nutrient solution within the mixing tank, ensuring it's suitable for the cannabis plants. The EC probe is connected to an electrical conductivity controller (EC controller), which controls the amount of fertilizer drawn from fertilizer tanks A and B into the mixing tank in equal amounts. When the EC probe measures an EC value inside the mixing tank below a predetermined level, the system stops the fertilizer flow.Furthermore, the fertilizer mixing tank is equipped with a Potential of Hydrogen probe (pH probe) to monitor the pH of the nutrient solution. This pH probe is connected to a Potential of Hydrogen controller (pH controller), which draws sodium hydroxide (NaOH) from the acid tank into the fertilizer mixing tank when the EC probe measures an EC value higher than a set level. This adjusts the EC and pH to maintain optimal levels at all times. The hydroponic cannabis cultivation system begins by setting times for water supply and recovery via inlet and outlet water control clocks. The inlet water pump, located in a large water tank, controls the water flow from this tank to the fertilizer mixing tank. From there, the water is sent to a 50 mm main pipe.A 20mm main pipe is connected to a 15-liter grow tank, which contains 4-inch pots for growing cannabis plants. The system delivers nutrient solution from a fertilizer tank to the grow tank, filling it to approximately 80% capacity (about 12 liters). This nutrient solution is delivered to the grow tank over a period of 12 minutes, allowing the plant roots to soak in it for 18 minutes. After this time, a timer controls the water outlet system, activating the pump in the fertilizer tank to drain all the remaining nutrient solution from the grow tank through the fertilizer tank and return it to the main water tank. This process takes 15 minutes until all the water is gone. Finally, the cannabis roots are allowed to receive oxygen for respiration within the grow tank for 45 minutes. This is the final step in the hydroponic cannabis growing system before nutrient solution is introduced again. One cycle of the system takes a total of 90 minutes, and this process is repeated 16 times per day.

Hydroponic cannabis growing system, according to claim 1, consists of the following operating procedures: The operating procedures of the hydroponic cannabis growing system begin with setting the time for water supply to the system and setting the time for water return. Through the inlet water control timer (10) and the outlet water control timer (12) by the inlet water pump (11) located inside the large water tank (1).Water is controlled from the large water tank (1) into the mixing tank (2), from where the water is sent to a 50 mm main pipe (14) which is connected to an 18 mm secondary pipe (15) to a 15-liter grow tank (16) which contains 4-inch pots (17) for growing the cannabis plants. The system will then supply 80 percent of the grow tank's nutrient solution, or about 12 liters, to the grow tank for 12 minutes. After this time, the cannabis roots will be immersed in the nutrient solution for 18 minutes. Once this time is complete, the outlet timer will activate to control the outlet pump (13) located in the nutrient mixing tank to draw all the nutrient solution from the grow tank through the nutrient mixing tank and back into the large water tank.
