<；P>；PROBLEM TO BE SOLVED: To provide a plant cultivating method intended for automatic operation through incorporating operation management technique of an operation administrator into a computer program, and taking in a biological response condition as data based on information of various sensors. <；P>；SOLUTION: This recycled plant cultivating method includes reusing waste water from indoor plant cultivation facilities in order to produce recycled water. The operation management of the indoor plant cultivation facilities is remote-controlled using one or a plurality of sensors for detecting a parameter which influences activation of useful microorganisms, and a data communication network connectable to the Internet. The remote control is executed by transmitting data which is obtained from a parameter detected by the sensor to a remote supervisory controller which is connected to the data communication network connectable to Internet, and automatically operating the indoor plant cultivation facilities by an operation control program. <；P>；COPYRIGHT: (C)2009,JPO&INPIT
