Effects of relative humidity, potting hardness of sphagnum moss, and fertilization on growth of Doritaenopsis Qevedo 'Sierra Vasquez' clone plant were investigated. Humidification affected plant growth favorably, but decomposition of sphagnum moss was promoted under humidified condition and plant growth was stunted subsequently. Potting hardness of sphagnum moss affected plant growth. Plants potted hard grew the best. Humidity control by bubbling air through water or NaCl saturated water increased humidity only when the weather was fine or cloudy in day time. Humidification of air around plants promoted vegetative growth. It was suggested that humidification promoted Doritaenopsis growth through enhancing phase 4 photosynthesis. Chlorophyll content was affected by fertilization and chlorophyll content was high when higher nitrogen was applied. Chlorophyll content was higher under lower humidity. Humidity showed no clear effect on spiking.
