Moving Orchids Outside After Summer Heat

[Nana Trish]

I'm wondering when/if I should move some of my orchids outside after the intense summer heat we have had in East Texas. Most of mine are Phals, a few are Cattleyas and 1-2 Epidendrum. They have been in my sunroom all summer with lots of windows and I keep a misting humidifier and a humidity tray going, as well as a ceiling fan on low. I know that some orchids need a change in temperature to encourage growth. So, if I should move them outside during day or nighttime this Fall, what would be the ideal conditions, temperature, etc.
