A greenhouse is a structure with walls and a roof made majorly of transparent material, such as glass, in which plants can grow in a climate regulated room. These structures range in size from small sheds to industrial-sized buildings. Many commercial glass greenhouses are production facilities for vegetables or flowers. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth.
The idea of greenhouses came from the Romans, it is said that the Roman Emperor ate cucumber-like vegetable daily and in other to provide this, the Roman gardens used artificial methods similar to the system of green housing to grow it and make available for his table every day of the year.
In the 13th century, greenhouses were built into house the exotic plants that explorers brought back from the tropics They were originally called giardini botanic(botanical gardens). In Nigeria, with the greenhouse system, we have the opportunity to be innovative with new breeds of plants and exotic agro-products like exotic flowers and other plants like apples and grapes that don’t naturally flourish in Nigerian weather.
