Cymbidium Flowering

[Paerata]

A second novice question. This is about getting cymbidiums to flower in Niagara Falls, Ontario. I have had no success. I left them outside until the end of October where they grew well- perhaps brought in too soon? Now inside and with central heating conditions are counter productive to spiking? Next year I should leave them outside for longer and when I bring them indoors my strategy should be? The 2 flowering phalas I have share the same stand in an eastern facing window. Is this an example of what is good for the goose isn't good for the gander?
