PROBLEM TO BE SOLVED: To provide hydroponics by which cultivation can be carried out even in a land unsuitable for farming in agriculture without selecting the land, plants unadapted for continuous cropping can continuously be cultivated, the quality and yield can freely be obtained by controlling the culture liquid and year-round culture can be performed with light labors. SOLUTION: Cultivation grooves and grooves for supplying a liquid and discharge the liquid are installed at the base of a cultivation tank and the grooves are used as a pool for stabilizing the liquid supply and circulation of the culture liquid and the amount of the supplied liquid. The nutrient and water are supplied from the grooves to roots of crops utilizing capillary actions of a nonwoven fabric 4 by using the nonwoven fabric 4 and a root penetration preventing sheet 3 without using a liquid supply tube for the nutrient and water to the crops. |
