The size of structure varies from small sheds to industry-sized buildings according to the purpose. Primarily, a greenhouse is a glass house whose interiors grow warmer when exposed to sunlight as the house blocks the greenhouse gas to exit. Therefore, while it may be cold outside the temperature is survival friendly and warm for the plants growing inside. Some greenhouses using high-end technology have installed equipment like heating and cooling system, lighting, screening installations and even computerized facilities to provide optimal growth conditions for the plants.
What are the Benefits of Polyhouse Cultivation
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. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. 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. Different techniques are then used to evaluate optimality degrees and comfort ratio of greenhouses, such as air temperature, relative humidity and vapour-pressure deficit , in order to reduce production risk prior to cultivation of a specific crop.

Polyhouse farming is slowly gaining popularity in India. A farmer can make huge profit from polyhouse farming. So let's start;. Polyhouse or a greenhouse is a house or a structure made of translucent material like glass or polyethylene where the plants grow and develop under controlled climatic conditions. The size of structure can differ from small shacks to big-size buildings as per the need.

You may have known shade cloth helps to cover and protect your shade loving plants. Even the writers of some articles are confused. The real difference only exists between shade houses and greenhouses as glasshouses and hot houses belong to the category of Greenhouse. In commercial nurseries the stages of plant growth are accommodated in different structures that increasingly expose the seedlings to outdoor conditions. Plants usually start in a glasshouse or a 'poly-tunnel' more commonly known and then to shaded structures and finally to a 'stand-out' area in full sun for final 'hardening off'.
Nowadays, many farmers are shifting farming to other professions due to insufficient financial protection. Climatic change is a significant challenge for the farmer. If we wanted to earn more profit from agriculture, we have to adopt modern farming techniques such as Greenhouse farming polyhouse farming , hydroponic farming, aquaponic farming. In India, we import many fruits, vegetables, and flowers from other countries and pay them very good money. What is Greenhouse? A Greenhouse is a framed structure covered with a transparent material and large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity. Greenhouse Technology is the technique of providing favorable environmental conditions to the plants.
The efficiency and productivity of a greenhouse operation is largely dependent on the type of growing structure used. Since there are many designs to select from, it is important to become familiar with the advantages and disadvantages of each. The following is a brief discussion of commercial greenhouses and their structural components. Generally speaking, there are three types of greenhouses: lean-to, detached, and ridge and furrow or gutter connected Figure 1. Few lean-to greenhouses are used for commercial production because of limitations in size. This type of house is the most popular among hobbyists.
Господи! - Джабба в отчаянии промычал нечто нечленораздельное. - Чем же отличаются эти чертовы изотопы. Никто этого не знает? - Ответа он не дождался. Техники и все прочие беспомощно смотрели на ВР.

Он немного постоял, наслаждаясь ярким солнцем и тонким ароматом цветущих апельсиновых деревьев, а потом медленно зашагал к выходу на площадь. В этот момент рядом резко притормозил мини-автобус. Из него выпрыгнули двое мужчин, оба молодые, в военной форме.
Новый стандарт шифрования приказал долго жить. Никому не показалось удивительным, что два дня спустя АНБ приняло Грега Хейла на работу. Стратмор решил, что лучше взять его к себе и заставить трудиться на благо АНБ, чем позволить противодействовать агентству извне.
Стратмор отрицает, что ТРАНСТЕКСТ бьется над каким-то файлом восемнадцать часов.
