PROBLEM TO BE SOLVED: To provide a method for growing leaf vegetable in a domestic plant factory by hydroponics installed in an indoor wall surface for which a perfect control system is not necessary.SOLUTION: A delivery desired date desired by a consumer and leaf vegetable whose cultivation is desired are integrated into data, and young plants in the timing of planting which can be harvested in two weeks are delivered on the desired date from a large-sized plant factory which performs cultivation from plantation to sprouting and seedling in response to an instruction from a data center. In a week, young plants of another leaf vegetable are shipped, and in the third week, the first grown leaf vegetable is harvested, and new young plants are planted in an empty water placement plate. Aluminum cultivation cases are installed in two levels on a wall surface under a domestic air conditioner indoor machine, and configured as a domestic plant factory. The front face of the case is clear, and a drawer type water placement plate in which young plants can be planted is adhered to the lower part, and an LED element is adhered to the upper part, and a power source cord is wired from an air conduct to an outdoor machine, and connected to a box in which a storage battery and a solar battery controller are incorporated, and a power is supplied from a solar panel.COPYRIGHT: (C)2014,JPO&INPIT【課題】完全制御システムを必要としない室内の壁面に設置する水耕栽培による家庭用植物工場において、葉菜類の育成する方法を提供する。【解決手段】消費者が希望した配達希望日と、栽培を希望する葉菜類をデータ化し、データセンターの指示により、播種から発芽、育苗までの栽培を行なう大型の植物工場から2週間後に収穫できる定植のタイミングの苗を希望日に配達する。1週間後には、別の葉菜の苗を発送し、3週目には最初の発育した葉菜を収穫し、空になった水入れプレートに新たな苗を定植する。家庭用エアコン室内機下の壁面にアルミ製の栽培ケースを2段に設置し、家庭用植物工場とする。ケースの前面はクリアで、下部には苗が定植できる引出し式水入れのプレート、上部にはLED素子を接着し、電源コードをエアコンダクトから室外機まで配線し、蓄電池と太陽電池コントローラーの内蔵されたボックスに接続して太陽光パネルから電力を供給する。【選択図】図3
