The present invention provides a greenhouse farming system with automatic control, which comprises at least one fuel cell module, an environment sensing control module, and a plurality of environment forming devices. In which, the fuel cell module has a plurality of inputs and outputs, wherein the inputs are respectively supplied with fuel and air, and then the outputs may respectively output the environmental products, such as electricity, thermal energy, carbon dioxide and water, and the environmental products are supplied to the environment sensing control module. The environment sensing control module may control the output of the environmental products, and is provided with a plurality of sensing units and control units for sensing and feedback control of multiple environmental factors, such as illumination, temperature, humidity, carbon dioxide concentration and water level, and product outputs. Each of the environment forming devices is configured in the interior of at least one greenhouse, and is respectively connected with the environment sensing control module to supply the environmental products outputted by the environment control module for respectively forming the growing environment and conditions required for plant cultivation in the greenhouse, such as illumination, temperature, humidity, carbon dioxide, and water supply irrigation.一種可自動控制之溫室耕種系統，係包括至少一個燃料電池模組、環境感測控制模組及複數個環境形成裝置，其中，該燃料電池模組具有複數個輸入端及輸出端，經由該輸入端分別輸入燃料與空氣後，由該輸出端分別輸出電力、熱能、二氧化碳、水等多項環境產物，該環境產物並輸出至該環境感測控制模組中，該環境感測控制模組控制該環境產物之輸出，並具備有複數個感測單元及控制單元，以供感測及反饋(feed back)控制該照度、溫度、濕度、二氧化碳濃度及水位等多項環境因素及產物輸出，各環境形成裝置設於至少一溫室內部，且分別連結該環境感測控制模組，以輸入環境控制模組輸出之環境產物，而分別形成溫室中所栽種植物所需之光照、溫度、濕度、二氧化碳及給水灌溉等生長環境及條件。
