Ali, our hybrid phals actually start blooming in the spring here. Usually around February and they stay in bloom though most of the summer. Spikes are started in the winter months when temps drop down into the upper 50's in our greenhouse.
If temperature in your area is not below 55 degrees at night - put them outside and let them get the cool down. Then, make sure they get plenty of filtered, bright light. Good luck!! (And not all phals need the cool down - some just need good, bright light to spike.)
