Phal. KS Happy Eagle sequential? Flower trigger?

[Laticauda]

I'm having a really hard time finding any details on the culture of this hybrid. Is it a sequential bloomer? I mean, what is the blooming habit? Does it continue to bloom on old inflorescences like the summer bloomers or is it a one and (mostly) done like the complex commercial hybrids?

Does anyone know what triggers blooming for these guys? Decreasing temps, increasing temps, daylength?

I'm also interested in anyone's other experiences with this hybrid or its parents. The photos of the flowers really caught eye so I bought one but the inflorescence was cut off! (It's still green.)
Thanks everyone!
