A hybrid environmental control system was designed and built in the multi-greenhouses. After the hardware system was developed, the software was designed and constructed for this project. A software was adequate for reading data from many sensors and operating side windows, top windows, curtains and fans in the two greenhouses. Separate programs for control of the hardware, written Visual basic, Turbo-C and Assembler computer language, were developed to make the hybrid environmental control system operate. The program was a menu driven program within Windows environment. The initial menu was easily implemented by pressing a keypad key(KPK) on the keyboard or a mouse. Continued manipulation of the KPK or a mouse enable the user to reach easily any of the sub modes in the many modes. This software proved to be a reliable program for the hybrid environmental control system in the two greenhouse.
