PROBLEM TO BE SOLVED: To provide a vertical hydroponic cultivation system and a vertical hydroponic cultivation method capable of preventing root rot of a cultivated plant and efficiently cultivating the plant by supplying a small amount of nutrient solution. SOLUTION: A vertical hydroponic cultivation cylinder 101 hung on a ceiling of a house or standing on a floor surface, a medium 102 that is detachably accommodated in the vertical hydroponic cultivation cylinder 101, and a culture medium from a nutrient solution storage tank 103. A vertical hydroponic cultivation system comprising: a nutrient solution supply means 104 for supplying a nutrient solution 107 to 102； and a vertical hydroponic cultivation cylinder 101 in which plant seedlings or seeds 106 are planted in at least one direction thereof. One or more vertical slits 111 or a plurality of openings for storing the culture medium 102, the water-holding sheet 121, and the breathable materials 122 and 123 sandwiching both surfaces thereof are used. A guide member 108 having a nutrient solution supply opening portion 108b at the lower end portion for guiding the nutrient solution 107 dropped from the nutrient solution supply means 104 to the upper end portion of the water retention sheet 121 is provided at the upper end opening portion of the cultivation cylinder 101.
