To provide a multi-controllable horticulture system that can simply reproduce complicated cultivation conditions that are different from individual characters of the plants and can save the energy for and simplify the cultivation works, for example, water supply, fertilization and the like.

The water-flow switching connector is made instantaneously detachable without water leak from the hoses for water flowing and supply to the plant pots and the hose for water flowing is passed through the plant pots which have each a dual structure so that the dual structure may develop the heat-insulating or cooling effect. In addition, the plant pots are each equipped with a cap type insect pests-repellent pot bottom net. The pumps for allowing the circulation water to flow, equipped each with a temperature controller are combined whereby the objective horticulture system is provided that can characteristically perform the multi-controls including temperature, water supply, fertilization, simple and easy attachment and detachment of the plant pots.
