Not sure about the plant you have there. But, if that is a brsdm orchid, treat it like an oncidium since it is a Brassia x Oncidium cross. These need high Oncidium orchid type light 1500-2000 foot-candles and temps of 70-90 daytime and 60-65 at night. 40 – 65 % relative humidity is ideal for growing this cross. Good luck!
