ABSTRACT:
A greenhouse device or complex in which the roof, sidewall, front and rear sides of a lean-to-roof, saddle-roof or three-quarter type greenhouse is lined with an outside glass sheet and an inner glass sheet providing a double wall on all sides of the greenhouse. Warm air is generated in a warm air generator in which gaseous fuel/air mixture is combusted for heating the outside air and the heated air so produced is mixed with a relatively cool air to produce the warm air at a temperature suitable for plant growing. The warm air so obtained is then forced to flow through the double wall structure surrounding the sides and roof of the greenhouse. The air which has cooled may be used as said relatively cool air in the warm air generator.
