## 5 Conclusions  
In conclusion, our study successfully developed an enclosed smart farming system aimed at addressing the challenges of traditional hydroponic systems by utilizing a misting-based approach. This system facilitates the efficient cultivation of high-value crops while optimizing water and nutrient usage, making it particularly suitable for urban environments with architectural constraints. The experimental results demonstrated the system's effectiveness in optimizing water circulation efficiency and precisely controlling the trace elements required by plants. Additionally, its mobility and spatial efficiency were highlighted as significant advantages. Furthermore, we validated the system's potential in extreme environments, such as water-scarce regions, by maintaining optimal conditions for crop cultivation through indoor environmental control. This underscores the significant contribution of smart farming technology to sustainable agriculture and water conservation efforts. Future \begin{table}
