Fans are the most efficient & economic way of providing air movement in all growing environments. The recirculation of the air helps to prevent stratification of temperature and humidity which is important to provide the crop with a more natural environment. Reduce the fluctuations of temperature & humidity by stirring the air will inhibiting the germination of fungal diseases thus reducing the incidence of fungal diseases in a crop & prevent stratification of temperature & humidity. Also improves the distribution of carbon dioxide in the grow area reducing the depleted zone around the active photosynthesizing crop canopy, making crop production higher.
Fan Controllers are indoor climate controllers, designed to be used with extraction & intake fans, they will maintain temperatures in an indoor growing environment through the use of a thermostat.
