Constant circulation of fresh air is an essential factor in health of indoor and greenhouses plants; The microclimate around plants have a significant effect on their health and development. Air circulation reduce climate differences and maintain a uniform temperature and humidity throughout a greenhouse. High humidity and condensation on plants lead to disease and other humidity related problems. Condensation problems occur when moisture in warm air condenses on cool leaf and covering surfaces.
