PROBLEM TO BE SOLVED: To provide the method developing a flower and a green environment by using wasted PET bottles as a hydroponic pot. SOLUTION: This hydroponic method comprises dividing a PET bottle into a raising bath 4 and a water storage bath 5 through cutting the bottle and joining the resultant two pieces together, extending a self-water-supplying string 8 to the water storage bath 5 so as to continuously feed the raising bath 4 with water, and hydroponically raising a plant by the nutrients contained in a hydroponic medium 7; wherein oxygen is inhaled by the temperature difference in the pot by penetrating air holes 6 through the overlapped position between the two baths, and air rises between the medium and the pot by stable dissolved oxygen and chimney effect. |
