In response to climate change and significant decreases of arable land in developing nations, vertical farming has emerged as a suitable alternative to the conventional method of farming with its use of modern technologies such as LED lights. Since previous literature on this subject had mainly focused on the effects of blue and red lights concerning plant growth, this research paper involved 620 nm (pink light), 550 nm (green light), and the combination of the colors in the color spectrum (white light) to expand the scope of the study. The facilities used for the experiment were a multiple-row vertical setup and a raised bed garden for the conventional setup. These setups were created using recyclable wood and furniture. Measuring tapes and finger-counting were utilized to detail the average height and number of leaves of plants within a specified group. One-way analysis of variance and repeated measures variance was used to show the variance or consistency of each group and significant differences between all groups. The results had depicted pink-colored LEDs to have yielded the best results by the end of the experiment with an average plant height of 10.39 cm and an average leaf number of 3.1. Overall, the vertical farming setups outperformed the conventional farm setup in terms of both mean plant height and number of leaves.
