Just wondering when it is advisable to take orchids summering outside INSIDE, after the temps drop at night.

I would imagine the first would be Phals (although mine are not outside) at 60 Degrees? Paphs too?

Most others would come in at 55 Degrees? Like Oncidiums and alliance, Catts, ??

What about mini cymbidiums? Do they enjoy a bit more of the colder weather?

Thanks.
