A workflow of this study. The light treatments were applied during the seedling stage to optimize the RGB photon ratio using response surface methodology. The optimal light for the seedling stage was depended on the shoot fresh weight of the mature plant at harvest, which was set as the production target. The selection of seedling parameters was conducted by comparing the root square mean error value between two response surfaces, shoot fresh weight at harvest and one of the seedling growth parameters. The value of multiplying the leaf area and SPAD of seedlings was selected and can be used for early decisions regarding seedling production
