Should my orchids spend the day outdoors?

[snappyguy]

I am very new to orchids and have read that a lot of people keep theirs outdoors at least part of the year. Here in Houston the weather is still in the mid-70's to lower 80's during the day. Would it benefit my Ascocenda and Beallara to spend the daytime outdoors? It's getting into the 40's and 50's at night so I'd bring them in at night. I have a patio that gets morning and late afternoon sun, but is shaded during the near noon hours, so I think this would be a great place for them. If there's no real benefit I'll keep them indoors to limit the potential for getting bugs on them.

Thanks,
Mark
