I know every year there are different theories on what makes phals bloom and it always seems to end up back at temperatures.
Temperatures do not affect phals flowering!
In fact giving it 12 hours of light in winter might work on warm growing phals but only because the plants have been tricked into thinking it is spring.
If it works consistently every year then that is great but not if it's just a one off method that tricks and then stresses the orchid because it isn't actually spring.
So why does it always revolve around temperatures?
Because there is a very simple reason. Nurseries do use temps to control flowering in phals.
They don't use temps to trigger flowering, they use temps to delay flowering till it is the right time and then they reduce temps thus no longer inhibiting flowering (If I remember constant day night temps above 26 degrees inhibits flowering)
So once the right time comes the temps are lowered and the phals flower.
This does not mean they were initiated to flower by lowering temps and doing so in the home would not have the same effect unless you were growing your orchid in very hot conditions.
My phals are triggered by day light hours regardless how warm or cold they are - as long as they are kept below 24 degrees which is no issue here in the UK
Does that mean all phals will consistently rebloom as long as temps are not inhibiting flowering?
Not necessarily, it does depend on their care and the light they receive but if cared for perfectly with enough light then yes they would rebloom every year even at a warmer 22 degrees C

edit: The picture looks really promising. I woudn't expect any flowers this year but if the same care is kept up it should be strong enough by autumn next year.
