Hi, I grow mine much as I do all my oncidiums. I give them light just a bit brighter than for phals. I water twice a week in summer and once a week to 10 days in the winter. I grow it cool in winter and am rewarded with good bloom. Your plant is very nice and am sure you will have great success with it. I also fertilize it weakly three times a month and flush it the fourth week. Hope this helps. You are really developing a great collection, Rich.
