As I grow outdoors I can only tell you how I grow mine, keeping them indoors like you do someone else will have to answer for that. They do like very bright filtered light, I water every 3 days and fertilize during the growing period every week, during the late fall and winter I only fertilize every 2 weeks. As to when do they bloom, if mature enough usually every time you get a mature new psedobulbs, some of mine will bloom twice a year some only once a year.
