Abstract
A system for controlling environmental conditions including irrigation or misting in greenhouses having a plurality of crop beds within one greenhouse enclosure. Aspirated enclosures have associated temperature sensors for measuring dry bulb temperature and humidity, the temperature of a surface over the bed and also a sensor of incident light over the bed. A computer is programmed with a task for inputting temperature data and for calculating the vapor pressure deficit over each bed and for inputting incident light data for measuring a parameter indicative of physiological crop age. A task establishes times for supply of water based upon the gathered data.
