Hydrophonic crop evapotranspiration (ETc) grown in a green house is differ than crop evapotranspiration grown on the field. Generally, crop evapotranspiration is predicted based on reference crop evapotranspiration (ETo) using field climatologically data and crop coefficients (Kc). This research aims to get an adjustment factor (f) for predicting hydroponic tomato evapotranspiration grown in a green house base on field climatological data. The results show that hydroponic tomato evapotranspiration grown in a green house is lower than tomato evapotranspiration grown on the field with average adjustment factor is 0.75.
