A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.
Greenhouses are frames of inflated structure covered with a transparent material in which crops are grown under controlled environment conditions. Greenhouse cultivation as well as other modes of controlled environment cultivation have been evolved to create favorable micro-climates, which favours the crop production could be possible all through the year or part of the year as required. Greenhouses and other technologies for controlled environment plant production are associated with the off-season production of ornamentals and foods of high value in cold climate areas where outdoor production is not possible. The primary environmental parameter traditionally controlled is temperature, usually providing heat to overcome extreme cold conditions. However, environmental control can also include (Greenhouses in Namakkal) cooling to mitigate excessive temperatures, light control either shading or adding supplemental light, carbon dioxide levels, relative humidity, water, plant nutrients and pest control.(Greenhouses in Namakkal)
The use of the greenhouse is mainly for producing seasonal and non-seasonal crops, for the production of high-quality flowers, vegetables, and the preparation of nursery prepared by tissue culture.(Greenhouses in Namakkal)
The design of greenhouse should be based upon sound scientific principles which facilitates controlled environment for the plant growth. Controlled environment plant production systems are used widely throughout the world to produce plant materials and products at a time or place, or of a quality that can not be obtained outdoors. Controlled environment agriculture requires far more capital investment per unit area than field agriculture and thus must essentially be correspondingly more intensive to justify investment costs. The greenhouse is a structure covered with a transparent material for admitting natural light for plant growth. (Greenhouses in Namakkal) The main components of greenhouse like structure, covering/glazing and temperature control systems need proper design for healthy growth of plants.
The duration of crop in greenhouse is the key to make the greenhouse technology profitable or the duration of production in greenhouses should be short. In this context, use of containers in greenhouse production assumes greater significance. The containers are used for the following activities in greenhouse production.
Namakkal is a Selection grade municipality and the headquarters of Namakkal district in the Indian state of Tamil Nadu. It is the first ISO 14001-2004 certified municipality in Asia for environmental management, specifically the provision and maintenance of water supply, solid waste and sewage management, town planning, lighting and other social services. Namakkal is known as the Egg City due to its large egg production and Transport city
Namakkal is a historic town with references back to at least the 7th century. The name Namakkal derives from Namagiri, which is the name of the single rock formation at the center of the town. The rock is enormous - 65 meters high and more than a kilometre in circumference. Over this massive rock, is a fort, Namakkal Fort
Since the 1960s, Namakkal has been a manufacturing hub of automobile body parts. Subsidiary auto industries and workshops scattered throughout the district have led to Namakkal’s fame as a ‘Transport Town’ in southern India. Poultry farms are another asset of this district. But, apart from enjoying the benefits of industrial progress, this region is also blessed with rich history, ancient temples, and enchanting natural sites. Namakkal’s Rock Fort remains a unique landmark. Pilgrims will discover several ancient temples located inside the rock-cut caves or near the picturesque Kolli Hills.
Most travelers are drawn to Anjaneya Temple because of a massive stone statue of Lord Hanuman. Reaching a height of about 13 feet, this magnificent statue faces another deity, Lord Narasimha. Built near the Namakkal Fort, this ancient temple is believed to be about 1500 years old. Kolli Hills is the most preferred weekend getaway in Namakkal. Part of the Eastern Ghats, the vegetation growing on this mountain range is considered to have medicinal values. The way to these hills passes through many treacherous bends before reaching attractions such as Arappalleeswarar Temple and the waterfalls of Akasa Gangai. Travelers can enjoy this sweeping hilly terrain from a number of viewpoints, including the ones at Arappaleeswarar Temple, Selur Nadu, Akasa Gangai, Telescope House, and Botanical Garden
