Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant growing system for growing plants around the perimeter of a building.

BACKGROUND ART Conventionally, it has been proposed to place plants on the roof or outer wall of a building and cultivate the plants using sunlight (see Patent Literatures 1 and 2).
Patent Literature 1 shows a roof greening device provided on the surface of a gable roof. A rooftop greening apparatus includes a cultivation tank in which plants are planted, a hydroponic culture circulation unit that circulates a culture solution between the cultivation tank, and a net provided on the surface of the roof.
Patent Literature 2 discloses a hydroponic cultivation system. A hydroponic cultivation system includes two hydroponic cultivation units having cultivation panels on which plants are planted, and a lighting device provided between the two hydroponic cultivation units and having a reflector. . In this daylighting device, the natural light taken in from the daylight opening propagates while being repeatedly reflected on the reflecting surface of the reflector, and the plants on the cultivation panel are irradiated with the light from the emission holes drilled in the reflector.

However, since the sun always moves, the rooftop greening device and the hydroponic cultivation system of Patent Documents 1 and 2 may not be able to irradiate the plants with sunlight sufficiently. Therefore, it is conceivable to appropriately adjust the angle of the roof in Patent Document 1 and the angle of the reflector in Patent Document 2 by using a driving device, but providing such a driving device increases construction and maintenance costs.
