A greenhouse is disclosed in which tubular curved members formed of standard unit lengths are used to form arched rafters while the same tubular members in uncurved form are used to form purlins. The tubular members are connected by suitable clamps to form a structural support for the roof of the greenhouse. A side leveling plate is provided on either side of the greenhouse to which the ends of the rafters are attached. The side leveling plate serves to anchor the rafters in the ground and also serves as a stapling surface for the covers placed over the roof of the structural support of the greenhouse. An environmental control system is provided in which the temperature, humidity and other environmental factors are controlled so as to provide enhanced growing climate for the tomato plants grown therein. Additionally, novel systems for correcting overwatering of the troughs as well as monitoring the water levels therein are provided.
