A greenhouse having a hollow framework structure (20) with water under pressure fluidly disposed inside characterizing a combined structural frame and water pipe. A number of spray nozzles (34) are attached to the framework at appropriate locations and drippers (60) are, likewise, attached. The nozzles atomize the water increasing the humidity inside the greenhouse and the drippers water the plants beneath. A transparent enclosure consisting of walls (42) and a roof (44) envelope the framework and are attached with straps (50). Air ciculation is achieved by windows (52) and vents (54) along with an optional fan (56).
