38: 595-607. The commercial production of orchids has been growing steadily in recent years, with particularly high demand among the genus Phalaenopsis. Consequently, the floricultural industry has begun investigating the response of Phalaenopsis cultivation under varying environmental conditions, including atmospheric CO 2 enrichment. The present review examines the work of Cho et al. (2020), who studied the response of two Phalaenopsis cultivars (Queen Beer Mantefon and Queen Beer Jupiter) to elevated CO 2 and nutrient supply over a period of 21 weeks. The experiment was conducted in a controlled-environment greenhouse at the Bulmuri Orchid Nursery, Paju, Korea, where twenty-month-old plants were grown in pots under ambient (~400 ppm) or elevated (~650 ppm) CO
