1 is an exemplary diagram illustrating a plant culture apparatus for arranging a tank tank in multiple stages in a plant cultivation space, and FIG. 2 is a schematic enlarged view of an extract of one cultivation space in FIG. Drawing.

First, referring to [FIG. 1], the plant cultivation apparatus installed in the plant factory is arranged in a multi-stage cultivation space (H1 to H5) formed horizontally long in order to utilize the space intensively.

Here, in each cultivation space (H1 to H5), a tank tank (not shown) in which plant groups grow is inserted and disposed, and a lighting unit is attached to the ceiling or sidewall of the cultivation space (H1 to H5) where the tank rack is located. do. At this time, the lighting unit irradiates light to the group of plants growing in the tank rack.
