PROBLEM TO BE SOLVED: To provide a blow off apparatus for plant cultivation which can aim at the cost cut of plant cultivation.SOLUTION: Multiple blow off members (5) which blow off air for cultivation to plants in a cultivation bed (2), and a conveyance member (6) which sends air for cultivation to the blow off members (5) are provided. The conveyance member (6) is provided with a wall part (8) on which the blow off members (5) are mounted and which faces to the cultivation bed (2) across plants (4). The blow off member (5) is provided with a circulating mechanism (11) for circulating air of a cultivation space (S) between the wall part (8) and the cultivation bed (2).SELECTED DRAWING: Figure 1【課題】 植物栽培コストダウンが図れる植物栽培用吹出装置を得る。【解決手段】 栽培ベッド（２）の植物に栽培用空気を吹出す多数の吹出部材（５）と、吹出部材（５）に栽培用空気を送る搬送部材（６）と、を備える。搬送部材（６）が、吹出部材（５）が取付けられると共に植物（４）を間において栽培ベッド（２）と向かい合う壁部（８）を、備える。吹出部材（５）が、壁部（８）と栽培ベッド（２）との間の栽培スペース（Ｓ）の空気を循環させる循環機構（１１）を、備える。【選択図】図１
