Abstract
This study was conducted to examine effect of different environment conditions in glass, PC, PET and PE greenhouses controlled by different environment control systems on the growth of green pepper. Light transmittance of 64.7% in the glass greenhouse was the highest among different green-houses. Air temperature was the highest in the glass greenhouse when ventilators were closed, and was the highest in the PE greenhouse when ventilators were open. Air relative humidity was the highest in the PE greenhouse during 24 hours. The amount of solar energy accumulated in soil was the greatest in the glass greenhouse and this energy released during the night escaped through covering materials. Latent heat and solar energy affected air temperature increased in greenhouses. The air temperature of glass greenhouse was 27.5
