Dependent variables are production of green lettuce and romaine lettuce and independent variables consist of harvest areas, seeds, rockwool, fertilizer A and B, and Labor. Data were analyzed using frontier production function and coefficient variation. The research showed that: there was a different of production efficiency between green lettuce and romaine lettuce using hydroponic NFT.  Green lettuce has lower efficiency rate but higher risk than romaine lettuce because diseases such as withered fusarium infected green lettuce. Key words : efficiency, hydroponic, lettuce, production, risk, time series
