How to make blooms last longer?

[glengary54]

I really think it is a tempurature issue, The following info comes from Orchid Wiz: "Rlc. Terri Henderson is composed of species of which 94% take intermediate temperatures, 82% take cool temperatures and 25% take hot temperatures. Grow this hybrid in cool to intermediate conditions, or 58°F to 75°F at night. It may be tolerant of hot (75°F to 85°F) night temperatures."

While it is in bloom I would move it to a shady area that has some air movement.
