Present invention relates to a plant growth apparatus, system and the method thereof. The plant growth method comprising a multi-layer plant cultivate frame installed in a greenhouse, and a plant placed in the multi-layer plant cultivate frame. A light guide unit installed in at least one side wall of the multi-layer plant cultivate frame to guiding the environment light to the multi-layer plant cultivate frame. An optical unit installed on the top of each layer of the multi-layer plant cultivate frame to reflecting and diffusing the environment light to the multi-layer plant cultivate frame. And, controlling the environment control of the multi-layer plant cultivate frame to create a suitable environment for the plant. Therefore, a plant factory with high harvested pre area and low cost is provided.本發明關於一種植物生長裝置、系統及其方法,其方法包括設置一植物栽培架於一溫室當中,該植物栽培架容置一植物;設置一導光單元於該植物栽培架之至少一側邊,以將一環境光導入該植物栽培架;設置一光學單元於該植物栽培架之每一層之頂部,以將該環境光散布於該植物栽培架;以及對該植物栽培架進行環境控制,以產生一適合該植物生長的環境。藉此,可提供一具有高單位面積產量與低成本之植物工廠。S81-S84...植物生長方法的流程步驟說明
