Micro climate control

Microclimate of green houses is important for better plant growth and greater yield. The dynamic behavior of the greenhouse microclimate is a combination of physical processes involving energy transfer and mass balance. The greenhouse microclimate can be manipulated by control actions, such as heating, ventilation, carbon dioxide enrichment to provide appropriate environmental conditions for crops. These modifications imply the additional use of energy in the production process.

Green house is a polyhouse or plastic house covered with polythene sheet. It is light in weight, easy to handle and cheaper in cost, resistant to hail, frost, over heating as well as very suitable for off-season vegetables cultivation. Vegetable growers can substantially increase their income by cultivation of vegetable under protected condition during off season as the vegetables produced during their normal season generally they do not found good returns due to availability of these vegetables in the market.

The horticulture field is developing new technologies for the development of quality products with higher productivity. Only quality products come under export for the world. Under protected cultivation the high quality produce can be achieved. The protected cultivation is technique of crop cultivation when the micro climate of the plant body is controlled partially or fully as per requirement of plant growth. The different designs of greenhouses developed for crop production varied from Hi-tech to shade net.

Humidity promotes the growth of moulds Credit: Infrogmation The majority of the health effects linked to dampness and moisture of buildings are those of the respiratory system. They range from irritation of mucous membranes, respiratory symptoms, and infections to diseases such as asthma and allergy. However , it is still not known precisely how dampness leads to these symptoms and which are the main substances responsible. Humidity problems in buildings may originate from leaks, condensation, or the ground.
