Phal pulchra throwing keiki's, how to get it to flower?

[Blueszz]

I've been reading up on Phal. pulchra and like your pulchra's, mine threw a keiki with probably a second keiki on the way.

What's the trick to get them to bloom? I read about a day/night temp difference from 10-12 C. I read about dud plants that refused to bloom for years.
I read about them being warm growers and about them being intermediate growers.

To get a temp difference between day and night and it being possibly an intermediate grower, I might grow it outdoors mid summer.

I have to mention mine might not be blooming size. I bought it blooming size but what I got was a relatively small plant with 1 long root. Treated it with Kelpak and it sent out many more roots.

Anyway, despite it maybe isn't mature enough to flower, I'm still hunting for info on how to flower them.
