This paper analyzed how the evapotranspiration (ETc) of lettuce in a non-circulating
hydroponics system correlates with the reference crop evapotranspiration (ETo) and the age
of the plant. Regression analysis was carried out to determine the relationship between ETc
with the ETo and the age of the plant. Fully developed and mature lettuce plants consumed
much water, and the changes in climatic conditions also caused a significant change in water
consumption during this stage of growth. The ETc of lettuce in non-circulating hydroponics
correlates with the climatic condition and the age of the plant. Water demand for lettuce
in non-circulating hydroponics is high at higher reference evapotranspiration and for mature
plants.
