A hollow plant pot includes a connection unit and a pot unit. The connection unit is hollow and includes at least one positioning part arranged on an outer surface of the connection unit and a hollow conjunction area. The pot unit is formed by blow molding and combine the positioning part of the connection unit to a wall of the pot unit through blow overmolding, whereby after the mold is opened, a hollow space of the pot unit is in communication with the conjunction area of the connection unit. The pot unit includes, after being molded, an inner layer forming a recessed accommodation area, an outer layer supporting the inner layer, a hollow space formed between the inner layer and the outer layer, and a water penetration hole communicating between the recessed accommodation area and the hollow space.本創作至少包括一連接單元及盆體單元所組成,其中:連接單元係呈中空狀,其至少包括有一設置於連接單元外表面上的限位部及中空狀的連通區;盆體單元係由一體吹氣成型的方式為之,且能以一體吹氣包覆成型的方式而將連接單元的限位部結合於盆體單元的壁面上,且於模具打開後,方能使盆體單元之空間區直接與連接單元之連通區呈連通狀態;又,盆體單元在成型後至少包括有一具有凹陷狀容置區域的內表層、一支撐內表層用的外表層、一夾置位於內表層與外表層之間的中空狀空間區、以及一連通凹陷狀容置區域與中空狀空間區之間的滲水孔所組成。1...盆體單元10...內表層11...外表層12...空間區13...容置區域133...滲水孔2...導管20...連接孔21...連接孔22...連通區23...限位部3...注水單元30...連接孔31...連接孔32...連通區33...限位部35...螺紋部4...透明視窗裝置40...透明元件400...連接孔401...連接孔402...連通區403...限位部48...浮球B...連接單元
