Experiments were carried out to develop an optimal nutrient solution for the single-stemmed rose (Rosa hybrida L.) 'Red velvet' in a closed aeroponic system. Plants were grown in 1/3, 1/2, 1, or 3/2 strength of the nutrient solution of National Horticultural Research Station in Japan (NHRS). Significantly less changes of pH and EC (dSㆍm-¹) in the drainage were observed in 1/2 strength treatment as compared to other treatments. The NO₃-N, K, Ca, and Mg concentrations in the drainage solution of 1/2 strength treatment were maintained at optimal levels.
