In an installation for continuous vegetable cultivation by the hydroponic system, a plurality of identical containers provided with lateral apertures are superimposed one on the other to create at least one vertical hollow column, provided at regular intervals along its axis with equidistant coplanar apertures (levels of culture) arranged for the insertion of plants. Means are provided for raising and lowering the column and for keeping it vertical, these means being in the form of a cable which is removably fixed to each individual container, and means for spraying nutrient liquid at the top of the column and collecting said liquid at the base, to recycle it to the top. In said installation a cultivation method is provided consisting of placing the plants in the highest container, waiting a number of days equal to the culture time in days divided by the number of containers provided in the column, removing the lowest container from the column, lowering the column by a distance equal to the height of the removed container, placing a new empty container on top of the column, inserting new plants into this latter and repeating the operation until the first filled container reaches the column base with mature plants.
