-The structural integrity of the Solidworks model with study main pot was evaluated using a Static 1(-Default-) study to determine the Static nodal stress (Stress1) under operational conditions. To simulate the weight of wet soil, a pressure load of 0.00206 N/mm² was calculated using the hydrostatic formula P = ρ · g · h (where ρ = 1400 kg/m³, g = 9.81 m/s², and h = 0.15 m), resulting in a total pressure of 2060.1 Pa. The model, constructed from PET (Part20), was constrained at its bottom surface and at a single screw hole to reflect its actual mounting configuration. The analysis reveals a maximum von Mises stress of 4.254e+05 N/m² (425.4 kPa), with significant stress concentrations localized around the screw hole and the top rim of the pot. While the overall structure remains stable, the Deformation scale of 2,055.71 highlights these critical regions, identifying the screw attachment point as the primary area requiring potential reinforcement to ensure long-term durability under the weight of the wet soil.</small>

 A mechanical error occurred specifically regarding the water flow through the solenoid valve. The system's gravity-fed water reservoir has a water head of 17 cm, which does not generate enough static pressure required for the component. The exact model tested is a pilot-operated solenoid valve, which requires a minimum working pressure range of 0.02 to 0.8 MPa to physically open the internal seal.
-To overcome this pressure limitation for the prototype phase, an 8W submersible pump will be added inside the water reservoir to generate the necessary force. The pump will push water through a translucent pipe. In order to control the submerged water pump second relay module will be used in order to communicate with ESP32 with same principal of work as the solenoid valve combined with first relay. To connect this to the system, a brass 1/2" female hose barb adapter will be used. The valve will screw directly into the adapter, and the smaller inlet of the adapter will connect to the pump's translucent pipe, completing the circuit from the reservoir to the valve. For the prototype the barb adapter has two threads, female one used to connect with the valve and the outer male thread used to connect adapter with threaded hole in side wall of the water reservoir.

 For the final production unit, the system will return to the original gravity-based design without the need for a water pump. To achieve this, the current pilot-operated valve will be replaced with a zero-pressure valve, such as a direct-acting solenoid valve or a motorized ball valve, which relies solely on gravity to allow water flow. Valve of this type also operates on 12 V, which will not require changes in circuit design.
