Vanda. The experimental design was randomized blocks arrangement with four replicates, the treatments consisted of two rooms, two sources and three levels of fertilization. Regarding production traits were evaluated plant height, plant diameter, number of leaves, stalk length, leaf area, canopy projection, total fresh weight, leaf fresh weight and productivity. Growth analysis was performed based on a weekly collection at 0, 7, 14, 21, 28 and 35 days after transplanting. The total and leaf dry mass and leaf area were used to calculate the specific leaf area, leaf area ratio, relative growth rate, absolute growth rate and net assimilation rate. Data were subjected to analysis of variance and means were compared by Tukey test (p
