The present invention relates to a module-type indoor hydroponic system, which comprises: a base having a main water tank； support frames to be stacked sequentially on the upper part of the base； a connecting bracket connecting one support frame with the other one to have a secondary water tank inside； an upper water tank connected to the upper part of the support frame located at the highest part to receive a culture solution from the main water tank through a main supplying pipe； a flower pot support accommodating a flower pot for hydroponics； a mount portion mounting the flower pot support on the support frame to communicate with the flower pot support at one side thereof and communicate with the secondary water tank through the support frame at the other side； and a secondary supply pipe connecting the upper water tank and the mount portion, or the secondary water tank and the mount portion, wherein the culture solution stored in the upper water tank or the secondary water tank is supplied into the flower pot support via the secondary supply pipe, the overflow of the culture solution flows down from the flower pot support through the insides of the mount portion and the support frame and then passes through the secondary water tank and is retrieved into the main water tank. Accordingly, module-type support frames are sequentially attached to or detached from each other, thereby enabling an adjustment according to the installation environment or the number of the growing pots to maximize the freedom of installation. In addition, since a flower pot support is mounted on the mount portion to allow the connection with water supplying and discharging structures, thereby enabling easy installation and maintenance thereof. Although the structure is very simple, there is no chance of leaking. Consequently, a sealing structure is not needed for preventing leakage, thereby minimizing manufacturing costs and improving reliability of the product.본 발명은 모듈타입 실내용 수경재배장치에 관한 것으
