This creation is about the improvement of a closed planting plant, especially for the re-improvement of the invention patent I507124 "closed planting plant". The main improvement is that the lamp and the potted plant are integrated into one, and the potted plant is unilaterally Designed to prevent workers from turning to affect plants, and the airflow is designed to spread from the center to the left and right sides and cooperate with the fog system to allow the plants to adjust temperature under natural temperature diffusion, effectively reducing the wind speed above and below the production area. The degree of temperature difference, avoiding the speed of plant growth, and designing the import and export of unilateral access, in order to avoid increasing indoor movement (risk of personnel entering and leaving) and reducing tariffs and saving costs.本創作係關於一種密閉式植栽工廠改良，特別是針對發明專利權I507124號「密閉式植栽工廠」之再改良者，其主要改良在於：將燈具與盆栽結合成一體，盆栽並於單邊設計，以避免工作人員轉身影響到植物，及氣流設計成由中央向左右兩邊擴散並配合造霧系統設計，讓植物能在自然溫度擴散下進行調溫，有效降低生產區上下的風速所導致的溫差程度，避免影響植物生長的速度，以及設計由單邊進出的進出口，以避免徒增室內動向(人員進出帶來的風險)與降低關稅、節省成本。
