In tropical regions the production of ornamentals is developed exclusively in naturally ventilated plastic greenhouses, which sometimes
leads to inappropriate microclimates with high temperatures and humidity that limit the productive development of plants.
The aim of this work was to study air flows, temperature distribution and relative humidity inside an alternative greenhouse designed
to produce rose (Rosa spp.). Three configurations of ventilation, side ventilation (SV), roof ventilation (RC) and combined
roof and side ventilation (RSV) were analyzed. The methodological development was based on the use of a previously validated
CFD-2D numerical simulation model, which showed an adequate fit between the measured and simulated data, obtaining MAE
and RMSE values for temperature and relative humidity of 0.44 and 0.47 °C, 3.99% and 4.04% respectively. The results obtained
for the predominant climatic conditions of the study region showed that the highest ventilation rates were obtained for RSV, with
values of 0.044 and 0.182 m3m-2s-1, this ventilation efficiency propitiated the generation of a homogeneous microclimate, with
temperature and relative humidity values adequate to produce rose (Rosa spp).
