Orchid...cactus! Blooming the things...

[Joshaeus]

Hi everyone! I have wanted to try keeping orchid cactuses due to their fantastic blooms, but am nervous about their blooming requirements - namely, their need for cool (cooler than 60 fahrenheit) nights for several months in fall (withholding water for most of that time would be relatively easy). Does anyone have experience with blooming these plants? If so, is the cooling period a strict requirement, or could I get away with just giving a dry period during the fall? Thank you
