The greenhouse uses a special type of glass which acts as a selective transmission medium
spectral frequencies. Specter comes from the word "spectrum".
In simple terms, the spectral frequency can be defined according to the following principle: viz
An object in the universe that emits, radiates or transmits light. This light is distributed along
The electromagnetic spectrum is determined by body composition.
Therefore, the greenhouse glass traps the energy inside the greenhouse and the heat in turn
It provides heat to the plants and the soil inside the greenhouse. The air is heated nearby
land and prevent it from climbing up and out of the bounds of the structure.
For example, if you open a small window near the roof of a greenhouse, the temperature drops
Significantly. This is due to the automatic self-ventilating cooling system. The autovent is simply that
Device used in greenhouses that maintains the temperature inside. this is the way
Greenhouses trap electromagnetic radiation and prevent convection (transfer of heat by
currents in a fluid).
Curious to know how the idea of a greenhouse came about? back to days
The Romans, who - as recorded history shows - were the first to create a protective structure
plants. Using heated pits, they laid slabs of rock to form primitive greenhouses. term
The "glass house", which is the correct name of this structure, was adopted in the 17th and 17th centuries
XVIIIth century.
However, at that time, the mistake was to believe that heat is more important than light
plants to thrive. Structures were built to exclude the entry of light, but the moment it was
The glass tax of 1845 was repealed and the design of greenhouses began to change.
Builders then realized that a curved roof rather than a flat roof allowed for higher concentrations of
sunlight, using iron instead of wood, the greenhouse can be structural
Improved and able to absorb more light
