Abstract
A system for regulating the supply of conditioned gases to an environmentally controlled enclosure. A greenhouse or warehouse in which plants are grown are supplied with gases having a controlled absolute humidity, temperature, and carbon dioxide content. The properties of exhaust gas from the environmentally controlled enclosure are measured, and the mass of bone dry gas provided, the absolute humidity, temperature, and carbon dioxide content in the enclosure are maintained, and the transpiration rate of plants in the enclosure is measured by comparing properties of conditioned gas at the inlet with exhaust gas exhausted from the enclosure, in order to enhance transpiration of the plants in the enclosure, to allow the grower to maximize growth or other selected properties of the plants under cultivation.
