NEW DESIGN GREENHOUSE

A greenhouse, also known as a glass greenhouse or hothouse, is a building specifically designed for growing plants. It is constructed of glass or plastic. Greenhouses are warmed by sunlight, which helps plants, soil, and air inside. Because planting can be done earlier and is less affected by climate, they are popular in subtropical and temperate countries. In arid regions, they also help prevent excessive moisture evaporation.

Glass is used as a building material for greenhouses because it is one of the optional transmission media for different optical spectra, and another function is its ability to concentrate and trap energy, warming the plants and air inside the greenhouse. This hot air sinks to the ground and is prevented from rising and flowing, so if only a small window is opened in the greenhouse roof, the temperature will drop significantly. This principle is similar to a basic automatic exhaust cooling system.
Greenhouses are typically used for growing flowers, vegetables, fruits, tobacco plants, etc.

Ventilation is one of the most important components of a successful greenhouse. Without proper ventilation, the greenhouse and the plants can easily become problematic. The main purpose of ventilation is to regulate the temperature to an optimal level and to ensure air circulation, thereby preventing the accumulation of plant pathogens (such as gray mold). Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important greenhouse crops to access pollination.
Heating, especially in cold climates, is one of the most significant costs. A major problem with greenhouse heating, relative to a building with solid, opaque walls, is the amount of heat loss through the greenhouse covering. This is because the covering needs to be structured to allow light to filter through.

Greenhouses protect crops from excessive heat or cold, and shelter plants from hail, sandstorms, blizzards, and pests. Controlling light and temperature within greenhouses can also convert some non-arable land into arable land.
Greenhouses can provide food and shelter for impoverished and famine-stricken developing countries that are unable to grow crops in deserts or frigid regions. Hydroponics, a cultivation method suitable for greenhouse use, is particularly well-suited for some inland areas.
