Blasted Kingianums

[nutgirl]

I've had a kingianum for about 4 years and I've yet to see a bloom. It has about 10 canes.
Finally, this year I had flower spikes developing but they all blasted. I would appreciate any pieces of advice.

It is grown outdoors all year in a sunny greenhouse. Temps can range from upper 30's - upper 80's on a sunny day in winter. I water weekly.
This year the upper temps have reached mid 90's on a couple of occasions.
Is that too high? Could it have caused my problem?

I had such high hopes for this.
