Abstract:
In warm climates, heat is removed from greenhouses either by ventilation only (VO), usually natural ventilation (NV) or by evaporative cooling which is more expensive. Microclimate and crop responses were investigated over several summer periods in rose, pepper and tomato crops grown, in most of the experiments, simultaneously in adjacent greenhouses with VO and evaporative cooling. Evaporative cooling was implemented with a Fan and Pad (FP) system while VO with fans in the pepper experiments and NV for the tomato and rose crops. In each treatment micrometeorological and plant parameters were monitored continuously over several days. For FP, greenhouse air temperature was always lower than with VO, as expected. Foliage was usually warmer than the greenhouse air with FP and cooler than greenhouse air with VO.
