Green houses are designed to support growth of crops under a variety of regulated environmental conditions such as temperature, humidity, light etc. Temperature being among them should be maintained at levels suitable for growth of a specific crop. Given that it may be costly to regulate the temperatures using electricity, energy cost can be reduced by use of automatic solar system because it is renewable. During the day the glass traps solar energy. The energy heats up the air which is then stored by the rock pebbles. During the night when the temperatures are low in the green house, the valve on the delivery duct is opened to allow warm air into the green house while at daytime temperatures is regulated by use of an automatic fan. The fan runs once the set temperature is reached and cools the greenhouse up to a certain point. The set point will be in accordance to the crop requirements. The design is cost effective, uses readily available materials and simple to construct which makes it ideal for small scale farmers.
