When it is getting cooler, I have to adjust watering times. I only dunk them up to the root zone only like you do during summer, and more often too, since our area is just so hot and dry. Then by Fall, I do not do the dunking method a lot. Greater interval in watering as temps go cooler. Especially after a long bloom season, it has that long rest time. And again, lots of air movement. I even open up the windows a bit to let cooler air in, it likes it, so it will try to get a bloom spike ready. A cool down triggers it. Sometimes too, since those orchids at the stores, have been there for too long, and we do not really know how long that media has been in there, it helps to repot with a new pre-soaked media.
Hope you can try again..just have to tweak some growing habits, I guess. That noid Phal has been in my care for the past 4 years, and it taught me a lot about what it likes. Sometimes I get a re-bloom on an old spike, sometimes not..but always, it will bloom for about 4 to 6 months, rest, make new leaves and roots, then it will ready itself to make a bloom spike between late Fall to early Spring, always in that period of cold season here.
