The invention discloses a hydroponic plant device with adjustable plant spacing, which comprises at least a long water tank with a notch for placing the culture liquid, and a plurality of loading platforms, each of which is disposed on the long water tank. a movable displacement, wherein the stage is provided with a plant hole, and at least one side thereof is provided with a positioning portion, and one end of the stage has a slot, and the other end is a plug portion； at least one driving member is disposed on the The long water tank is located on the opposite outer side of the loading platform； at least one blocking member, each of the blocking members is coupled to each of the driving members. Each of the stages of the present invention respectively places the seedlings into the plant holes, and the stages are sequentially disposed in the long water tanks, and each of the stages is adjusted by the respective positioning members to adjust the respective plant holes. The spacing, and the spacing of each hydroponic plant to adjust its spacing, so that different watering plants of different ages can achieve different optimal growth space, not only can improve the quality of hydroponic plants, but also effectively use limited space, Increase the yield of cultivated plants.本發明係揭露一種株距可調的水耕植株裝置，至少包括有：一長水槽，其係具有一槽口以置入培養液；複數載台，各該載台係設置於該長水槽上可活動位移，而該載台設有一植株孔，及其至少一側各設一定位部，及該載台一端具一插槽，另端為一插部；至少一驅動件，其係設置於該長水槽，並位於該載台二相對外側；至少一擋件，各該擋件係連結各該驅動件。本發明各該載台分別係逐日將小苗置入植株孔，該載台再依序設置於長水槽，而各該載台間藉由各該擋件抵頂定位部，得以調整各植株孔的間距，而因應各水耕植物逐日成長而調整其間距，讓不同日齡的各水耕植物間獲致不同的最佳成長空間，不僅能提昇水耕植物的品質，更能有效運用有限的空間，提高培植栽種的收成量。
