Phalaenopsis Rebloom?

[Fenix]

I have a Phal that is about a year old. After its blooms fell I continued to care for it and it has since grown several new leaves and roots. I've also been fertilizing, and the plant looks quite healthy. But it has yet to Rebloom. When can I expect this? I thought that by this time I would be getting a new flower spike.

I'm also considering inducing the bloom since a lot of material I've read has said that a temperature drop at night is necessary for a Rebloom. If I do this, how long of this exposure would it take before a bloom appears on average? Days? Weeks? Months? And if the flower spike does appear, do I continue to subject it to the temperature fluctuation or should I move it back to the original conditions?

Thanks.
