Effects of the evaporative cooling system in greenhouses used for roses and carnations


, : Effects of the evaporative cooling system in greenhouses used for roses and carnations. Acta Horticulturae (43(1)): 113-123

Roses (cv. Super Star on R. indica major and R. canina) and carnations (cv. Super Cardinal) were grown in a glasshouse (A), in a plastic house (B) provided with a cooling system, and in an uncooled plastic house (C). Cooling was provided by humidifying pads, water sprayers (1.5 l/min/m2) and fans, changing the air volume of the houses 60-65 times/h. The cooling system reduced the temperature by 3-7 deg C in different parts of the house.
