As usual for me, I'm coming into a thread a bit late.
I'm responding to the original post with its concerns about temoperature along with other growing requirements for orchids.
One thing to keep in mind, orchid cultivation requirements are little more than a best guess as what to try to setup for them.
They are not rigid rerquirements.
One needs to experiment a bit to see what they can provide that meets an orchid's needs.
Individual plants can have different needs fron the average in their species.
I maintained winter night temps no lower that 65°F with days about 72°F using a programable thermostat that allowed setting day and night temps for summer and winter.
Summers had higher day temps, especially with doors being left open for higher temps and air circulation with fan use mandatory in winters.
I also used a humidifier set on high to offset the cold dry sub zero winter days.
It never did a very good job, but it did help.
Day length varried from 19 hrs summer to 4 hours winter.
After all, I lived there too and had to provide conditions I could live with.
My experiences convinced me that many orchids, Dendrobiums in particular, do quite well at normal houdehold temps.
Some of these plants are as much as 15 years old.
Some ended up being 20 years old by the time I divested myself of orchids and left AK.

The plants on the LH end of the top 2 rows are Den. aphyllums, 2 of the 3 in the next pic.
