    When it was autumn I moved my phal into an unheated garage the coolest part of the house for 3 weeks only during the night though at day I move them back to the normal position the sudden shock and cool exposure lead them to spike I didn't even keep accurate temp readings I just used my human senses

    Thank you all for the scientific comments. i will try to be more observant to my orchids' environment.

    i have been searching what will trigger the flower spike for orchids, or do orchids have blooming season like roses... but no luck!
    at least this orchids "rooty" one, is healthy like the my other orchids...
    re. decrease of temperature during fall, i think it is hard to say... we just had " indian summer" last monday and tuesday (90's in the a.m. and 80'- upper 50's at night) and sudden drop to mid 70's in the am and 50's at night. too unpredictable.
    But i am hoping this orchid is just adapting to it's new home. maybe the blooming time for her is "SOON"!!!

    more scientific info from Michigan State University.
    yes, 4-6 weeks of cooling ( low temperature 63- 77 degrees F) plus adequate light will help orchids develop 1-2 flower spikes.

    Different orchids have different stimuli.

    In some phalaenopsis (not all) it's the average temperature thing, with some cattleya species, it's a response to changes in day length. Some are strictly seasonal, especially those that originate in places with extreme seasonal variations in rainfall. Some bloom upon maturation of growth, while others bloom before a new growth beings, and others do so just when that happens.

    Add the confounding factor of hybridization, and hoo-boy!, you end up doing what you think ought to work, and hope for the best.

    Growing in a greenhouse, I do get some seasonal variation, which I have little control over, so the best thing to do is grow a plant as well as you can, and when it is ready to bloom, it will.

    Do you remember my orchid w/ lots of aerial roots but no flower spike??
    after 2 yrs of waiting, i am enjoying my first flower spike from her!
    hope my pictures are good enough that you guys could see her color ( greenish white). after the the cold snap during the winter dec- jan2013, low temp at night and mild temp triggered the flower spike. still enjoying her flowers for 2 months already..

    It's so nice when learning patience from your orchid, you actually get a pay-off like that! What a pretty flower.
