In this study, the growth indices of leaf length, leaf width, number of leaves, fresh weight, T/R ratio, and leaf shape index of baby romaine lettuce grown under various light wavelengths were compared and investigated. During the interval between the 7th and 21st day, the leaf length was the longest in lettuce grown under red (R) light, followed by that grown under QD2 light mixed with B + R + FR light. The leaf width was the widest under the QD1 and QD2 light conditions, whereas the red (R) light caused the narrowest leaf width. The highest number of leaves occurred under QD2 light conditions, followed by QD1, with the least number of leaves occurring under the blue ( B) l ight t reatment. T he h eaviest t op fresh w eight w as o btained u nder the QD2 l ight conditions, followed by QD1, although the root fresh weights in the QD1 and QD2 light treatments were higher than those in the other light treatments; no significant differences were observed between the red (R), QD1, and QD2 light treatments. The leaf index was the highest in the fluorescent lamp (FL) treatment, which also yielded the longest leaf, followed by the red (R) light treatment, whereas the QD1, QD2, blue (B) + red (R), and blue (B) light treatments showed the lowest leaf index values. Taken together, the results suggest that QD2 light might be an effective source of artificial light in the closed plant factories growing romaine lettuce because of the better growth indices compared to those obtained under other light treatments and the control (natural light).
