Temperature Question

[DavidK]

Hi Everyone ,
I have just been bitten by the "orchid bug" and have a few plants , mostly cattleyas and as I'm getting into my new addiction and hoping for flowers I come across some orchid information on sites saying they need to drop down into the 60's at night .
I live in Central Florida where the night temperature doesn't drop that low in summer , normaly mid to high 70's ! do you think this will stop my plants from flowering ?
All my plants look healthy with nice mid-green leaves except one which I have moved about to try to get it to look healthy , it is a cattleya hybrid , and it's leaves just stay dark regardless of where I put it .
I'm growing my orchids in the screen room which faces west , and getting good light & humidity at this time of year , do you have any tips for me ?
Thanks ... David
