Abstract: A study was taken up to determine the properties of the nutrient solution for the hydroponic system under shade net house and to study the micro climate parameters inside and outside the shade nethouse. EC and pH of the nutrient solution were observed for the hydroponics system. pH varies from 7.5 to 9.2 and EC varies from 1.14 to 1.43 ds/m. Temperature inside the shade net house was having slightly lesser value than outside atmospheric at range of 1.6 ºC to 2.7 ºC during the experiment period. Maximum and minimum temperature, relative humidity and light intensity were observed for the effective crop growth period.
Keywords: Hydroponics, Shade nethouse, Micro climatic parameters
