Hydroponics are there in the community in generalare still using manual systems and relatively costly in terms of time, among others, to measure acidity(pH) and nutrients in plants using plant maintenance hydroponic and determine the volume of waterthat is used to optimize the system that has been realized that , Realizing a temperature regulatingsystem and humidity desirable, but it is still done manually. (Bonorowo, 2014)technique used inhydroponics is NFT (Nutrient FilmTechnique).The basic concept of NFT (NutrientFilmTechnique)is amethod of cultivation with plant roots grow in shallow layers and nutrients to circulate so that theplants can get enough water, nutrients and oxygen]]>
