CASE STUDY: TO RAISE GROWTH OF ARGICULTURAL PRODUCE BY CONTROLLED SPECTRUM RATIO RGB OF LED

This paper proposed the case study to raise the growth of agricultural produce by a controlled spectrum ratio Red(R), Green(G) and Blue(B) of LED. This study focuses on the optimal ratio of R, G, and B to the 3 flower plants (Chrysanthemum, Carnation, and Lisianthus) which are essential for industries in Thailand. To evaluate the performance of proposed method, the height, the dimension of leaf, flowers are measured in case of original and each controlled ratio of Red, Green and Blue. The experiments are performed with all controlled environment. The results which compare with conventional method show the different positive and negative results in different R, G and B composition.
