Do phals have to show a spike before stopping temp changes?

My phals had been outside for August in east sun with a shade cloth, the beginning of September they had to be brought in because it was going below 60 at night. They are now in a south window (only room I can let get down to 60 at night) with a sheer curtain. There has always been at least a 10 degree temperature change day/night for these past 2 months. 2 are showing spikes, the others look good, new roots, etc, but no spikes yet. The problem is I need to move them out of the south window because all of the other orchids are coming inside and need that sunny spot. The area they will be moved to will have a steady temperature.

Do the phals HAVE to show a spike before I can take them out of the window, stop giving them temperature changes, and put them into a more steady temperature area? Or will a spike show up later, assuming they actually want and are ready to flower?

Thank you :)
