The present invention relates to a water tank required for hydroponics of ginseng. Provided are a method for making water tank frames to strengthen the solidity of the water tank to bear the weight of water by making frames in four sides of an upper part of the rectangular water tank by bending and the water tank for hydroponics of ginseng which comprises: a bed holding device making air flow smooth by mounting a bed holding device having long both sides wherein a bed is inserted and held on the height to keep a space from water surface so as to fix the bed to enable an upper board, the bed, to be easily inserted and to keep a space between the bed and the water surface; and a remodeled nanobubble generator with a timer function connected to a water inlet port and a water outlet port formed in a lower end of the water tank and supplying nanobubbles, thereby spreading nutrients in a culture medium over the water tank, preventing occurrences of contamination and algal blooms by purification and sterilization, preventing environmental pollution by increasing dissolved oxygen in the culture medium so as to repetitively use the same and minimize discharge of a waste culture medium, and promoting growth of the crop. |
