I found this bit on Taisuco's website.
Forcing Flower:64 oF night temperature and 77 °F day temperature are ideal temperature settings for forcing flower of most Phalaenopsis varieties. Uniform spike initiation can be expected in 4-6 weeks, and plants will be ready for sale in another 3 months with one to two flowers open. Time required may vary, depending on variety and plant conditions.
After spike initiation, the time needed to the first flower open can be manipulated, either push it by increase the temperature or slow it down by low the temperature, depending on when market need it. Increasing the temperature will run a risk of getting fewer bud counts and definitely high energy cost. Low the temperature might run a risk of bud drop caused by the cold.
Light is also an important factor in forcing flower process. Higher light intensity will give better flowering quality, only if the light does not reach the level of burning the leaves or increasing the temperature in the greenhouse too much.
