How to make blooms last longer?

[got ants]

Not sure this has been addressed before, as I couldn't find it....

I have Blc Terri Henderson "Paul" that just started openening up on friday, and is already wilting the first of four flowers. I doubt it will make it to the next local orchid society (next monday).

I grow outside, and keep outside, in a pergoal with about 40% sunlight. It get a good breeze being high in the pergola, but maybe still too much heat. Should I be bringing my flowering catts inside? They would then be in low humidity, no air movement, and about 75% f.
