ABSTRACT:
A method and apparatus for increasing the growth of plants (24) in a greenhouse (12, 13) or other protected area is described. The method and apparatus regulates the amount of carbon dioxide to which the plants are exposed and the temperature of the atmosphere as a function of the amount of light in a pre-selected temperature range and vents the greenhouse to outside air above the temperature range. The method preferably uses a computer (10) and microprocessor (11) for detection, analysis and adjustment of the growth variables.
