Light : The plant must be grown in diffused light. Besides sunlight high-pressure sodium or metal halide fixtures can be use as artificial light for the orchid.

Water : We must water the plant when the mix just approaches dryness. Oncidium prefer clean water without a lot of minerals content. For best grow we must use distilled reverse osmosis or rainwater. We cannot use softened water.

Humidity : The ideal humidity level for these plants should be kept at 40% or above.

Temperature : Oncidium plant prefers night temperature up to 60˚ - 64˚ Fahrenheit during fall, winter and spring months. And ideal daytime temperature is up to 70˚ - 85˚F.

Flowering : More flowering generally take place during fall and spring. Many hybrids can bloom 2-3 times per year. The flower spiker on Oncidium generally grows to a medium or tall length and branch out in several directions.

Repotting : Repotting can be done every 1 to 2 years as the mix break down or as plant outgrows the pot. Plant that is potted in a bark mixture must be pulled out carefully.
