PROBLEM TO BE SOLVED: To provide a cultivation facility for simply supplying rainwater at low cost to a nutrient solution-supplying device for cultivation.SOLUTION: A cultivation facility comprises a rain sensor 116, a rain water-collecting device 111, a rainwater-supplying path 114 for supplying the collected rainwater to a raw water tank 44 of a nutrient solution-supplying device, and a control device for controlling the supplying of the collected water to the raw water tank 44 of the nutrient solution-supplying device. The cultivation facility is configured to be capable of switching the following configurations: a configuration for not using rainwater, in which the collected rainwater is not supplied to the raw water tank 44 regardless of detection by the rain sensor 116 and water is supplied from another water source to the raw water tank 44 as the water level falls below a predetermined level； a configuration for supplying rainwater on a priority basis, in which the collected rainwater is supplied to the raw water tank 44 regardless of detection by the rain sensor 116 and water is supplied from another water source to the raw water tank 44 as the water level falls below a predetermined level； and a configuration for use of rainwater, in which the rainwater collected by the rainwater-collecting device 111 is supplied together with water from another water source as the water level falls below a predetermined level.SELECTED DRAWING: Figure 7【課題】簡単で且つ低コストに栽培用の養液供給装置への雨水を供給する栽培施設を提供する。【解決手段】降雨センサ１１６と、雨水回収装置１１１と、回収した雨水を養液供給装置の原水タンク４４へ供給する雨水供給経路１１４を設け、回収された雨水を養液供給装置の原水タンク４４へ供給する制御を行う制御装置を設け、降雨センサ１１６の検知に係わらず回収した雨水を原水タンク４４へ供給せず、水位の所定以下の低下に伴って別の水源から原水タンク４４へ水を供給する雨水不使用形態と、降雨センサ１１６の検知に係わらず回収した雨水を原水タンク４４へ供給し、水位が所定以下に低下したときには別の水源から原水タンク４４へ水を供給する雨水優先形態と、水位が所定以下に低下したときに雨水回収装置１１１で回収した雨水と別の水源からの水を共に供給する雨水併用形態に切替可能な構成とする。【選択図】図７
