Thanks everyone.
I have added some chc to cover the roots and now will wait for flowers.
Is it a spring bloomer? any special care to promote flowering?
I have seen them bloom twice a year.... spring and fall
Use a good fertilizer, RO or distilled water, good air movement, bright but not direct light, and day temp in the 65-80 f and night temps 55-65 f (you need the temp drops) for best results.
