A plant cultivating system is disclosed. The system comprises a frame, at least one container, at least one lamp and a control module. The container has a compartment. The lamp has a housing, a plurality of lighting modules and a driving assembly. The lighting modules are mounted on the housing and face the compartment of the container. The driving assembly drives the housing to move relatively to the container in a linear manner. The control module has a processor, a sensing assembly and an interface unit. The processor electrically connects to the sensing module, the interface unit, the lighting module and driving assembly. The sensing assembly is mounted in the container. The processor adjusts the luminance of the lamp based on the luminance requirement of a plant.一種植物培育系統,包含:一框架;至少一培養槽,固設於該框架,且該培養槽設有一容置空間;至少一燈具,設有一殼體、數個發光模組及一致動組件,該發光模組設於該殼體,且朝向該培養槽之容置空間,該致動組件驅使該殼體相對該培養槽線性移動;及一控制模組,設有一處理單元、一感測組件及一介面單元,該處理單元電性連接該感測組件、該介面單元、該燈具之發光模組及致動組件,該感測組件設置於該培養槽;其中,該處理單元係依據一植物光源需求而調整該燈具所產生之發光源。1...框架11...柱體12...樑體2,2a,2b...培養槽21...容置空間21a...第一分隔空間21b...第二分隔空間22...分隔件3,3a,3b...燈具31...殼體311...設置面312...螺接部313...滑軌32...發光模組33...致動組件331...動力元件332...螺桿333...定位件34...遮光件4...控制模組41...處理單元42...感測組件421...光感測器422...液位感知器43...介面單元44...通訊單元5...供液模組51...容器52...泵浦53...導管54...電磁閥
