Abstract—Dendrobium Sampran, a vibrant orchid hybrid, holds immense economic significance in Southeast Asia’s floriculture industry. This study investigates the effects of photoselective shade netting on the growth of this prized species, focusing on the critical roles of temperature and humidity. This study reveals that set-ups 2B and 3B, 50% and 75% green net, significantly enhance growth metrics such as plant height, number of leaves, and flower production. Specifically, set-up 3B achieved an impressive F-value of 283.65 for humidity, underscoring its critical role in promoting vertical growth. In contrast, set-up 2B consistently yielded high flower counts and leaf development. The Analysis of Variance (ANOVA) results highlighted the negligible impact of temperature on growth, emphasizing that humidity is the driving force behind the successful cultivation of these orchids. By implementing these optimal set-ups, growers can enhance the health and productivity of Dendrobium Sampran, ensuring a thriving yield that meets the demands of the floriculture market. By implementing the identified optimal set-ups, growers can unlock the full potential of Dendrobium Sampran, driving economic growth and environmental stewardship in the floriculture sector.
