Sunlight plays an important role in the photosynthesis process of orchid plants for optimal growth. Cymbidium orchid plants, for example, require a range of sunlight intensity between 3500 lux to 4000 lux (B.V., 2023). When sunlight intensity is low, the photosynthesis process will inhibit orchid plant growth and flower formation (Sudarso et al., 2020). Therefore, it is important to ensure prop…
