How to flower Christensonia vietnamica

[okieOrchid]

Hello,
Does anyone know if any special conditions need to happen to flower Christensonia vietnamica ?
I have a 2 couple of these plants. They are about 5 in tall, 5-6 in leaf span and I was told by the seller that these plants are Blooming size. I have had them for about 1 year now but still did not see any spikes forming yet. Roots are growing ALL over the basket.
I have them in direct sunlight for at least 6-8 hours, and water them twice a week in summer and 1/week in winter, with an almost daily spray. They are in a wood basket with a couple of barks and some coconut fiber.

Thanks

Hi,

Christensonia vietnamica needs a little less light than Vanda but still bright light. Let say as Aerides.
They are not difficult plants to make bloom. Flowering season is from spring to late summer or fall.
I think that direct sun for 6 to 8 hours is quite heavy but I don't know how strong is the sun where you live...
