PROBLEM TO BE SOLVED: To realize excellent cultivation and to improve workability, since a conventional cultivation assistant device, such as a heating piping, has problems: that the device cannot effect on entire plant which grows in vertical direction since the device has a construction where the device extends in forth and back direction and a construction where the device topically effecting on a point near the growth point of the plant； and that it is thus considerable that light receiving is restricted and operation from a passage is obstructed due to a large-scale structure thereof in which, for example, cultivation assistant devices extending in forth and back direction are arranged on the same cultivation line but vertically different positions and effects on the plants planted at the vertically different positions.SOLUTION: A cultivation facility comprises a plurality of cultivation units for cultivation of plants on a pair of right and left cultivation lines in a manner where the cultivation units are arranged in parallel between the right and left cultivation lines. A passage (9) in forth and back direction is arranged between each right and left pair of the cultivation units. Cultivation assistant devices (121, 122) suspended from upper side of a gap between the pair of right and left cultivation lines and extending in vertical direction are arranged in a manner where the devices may move in forth and back direction.【課題】 従来の暖房用配管等の栽培補助用装置は、前後方向に延びる構成であり、植物の生長点付近に局所的に作用する構成であり、上下方向に延びる植物全体へ作用させることができない。そこで、例えば前後方向に延びる栽培補助用装置を同一の栽培条間に上下に複数配列する等して、植物の上下にわたって作用する構成とすることが考えられるが、構造が大掛かりなものとなって植物への受光を制限したり通路からの作業の邪魔になることも考えられる。本発明は、良好な栽培を行うと共に、作業性を向上させることを課題とする。【解決手段】 左右一対の栽培条にて植物を栽培する栽培ユニットを左右並列に複数設け、各々の栽培ユニットの左右間に前後方向の通路（９）を形成し、左右一対の栽培条の左右間の上方から吊り下げられ上下方向に延びる栽培補助用装置（１２１，１２２）を、前後方向に移動可能に設けた栽培施設とした。【選択図】図１２
