cornu cervi chattaladae 4N refusing to bloom

[camille1585]

I don't have this orchid, but do have a few Phals with high light requirements.

What sort of light is higher light? Orchidwiz says 1200-1500fc, but that they reportedly produce more blooms when light is high enough to turn leaves yellowish. In habitat, winter is the brightest season (1500-1800fc). They also add that winter is the driest season, with most water coming from dew, and humidity is around 60%, so they advise restricted watering: occasional early morning mistings between infrequent light waterings. Does not say if this is required for blooming. It also says that this plant should be in near continuous bloom!

I'm in the Netherlands, so at a latitude similar to southern Canada. Nearly all my Phals live on shelving in front of a south facing window, and are in full sun from mid-late morning to late afternoon. In the summer the sun is so high that there is little direct sun at the hottest hours of the day.
