Abstract: This study conducted twice the growing of lettuce in DFT system and aeroponics method with
different light combinations.
(1) Deep flow technique system(DFT) : The lettuce was grown in DFT system and taken image. Then
image analysis and absorbance was analyzed to know the correlation.
(2) Aeroponics system : From the image of grown lettuce and HPLC, the contents of the major
functional elements of anthocyanin
