Interesting Facts about Greenhouses
Greenhouses have been in use for at least 2000 years. The earliest examples of course were not anything like the polycarbonate plastic greenhouses available today, but the basic concept was the same. They need to provide an environment which protects plants from the extremes of cold and heat, winds and the damage caused by various pests. Greenhouses are also used to extend a plant's growing season and even to enable a gardener to grow non-native plants which would not survive in the open.
One of the first known examples of a greenhouse was the specularium constructed for the Roman emperor Tiberius who was advised by his physicians to eat a cucumber every day. This greenhouse apparently featured stone walls and a translucent roof which was made from small pieces of mica to let in the sunlight. Heating was provided by fires burning against the outside of the stone walls.
The modern greenhouse concept was developed in the 1500s by botanists and collectors interested in propagating exotic species of plants discovered by explorers. An early greenhouse with glass roof and walls was built in Holland by the French botanist Jules Charles who wanted to grow tropical plants. (The Netherlands has certainly maintained and expanded this tradition – huge areas of land are covered by greenhouses and hothouse vegetables and flowers are grown in enormous quantities; if you look at The Hague, Netherlands on googlemaps.com you will see that almost half the city is made up of commercial greenhouses. Visitors to The Hague notice the glow in the night sky of lights which are left on to assist plant growth).
During the 1600s glasshouses became fashionable with the aristocracy in Europe, and increasingly elaborate and expensive examples where built in various places. The orangerie at the Palace of Versailles constructed during the reign of Louis XIII was over 150 metres long, 12 metres wide and nearly 14 metres high. Of course, the immense cost of such a project was of no consequence to the king, but as glass was very expensive in those times greenhouses were strictly a luxury item for the very wealthy.
By the mid 1800s glass was being produced in large quantities and the cost was greatly reduced. Glasshouses became more common and some amazing examples were built. One which still stands is the Palm House in the Kew Gardens. This took 4 years to build and was completed in 1848. It featured an iron framework with open spaces free from pillars and utilised design concepts based on shipbuilding, which was also undergoing the radical change from wooden construction to iron.
Since then design and construction has evolved, and these days greenhouses are readily available in a wide range of types, sizes and price ranges. The frame construction, traditionally using timber, has moved through steel to extruded aluminium sections. Nowadays, glass is often replaced with plastics such as polycarbonate which has excellent light transmission qualities and is virtually unbreakable.
