1st Zygo question

[Dollythehun]

Just got my first Zygo, an "Advance Australia." I've read up on the care and I think it will be happy here but I have 1 question:

Of these two locations which would make it happiest? My sunroom where light is very bright ( on a sunny day, blinding) but temps are steady 68-70f the rh 50-60,% OR my greenhouse window with my Phals where the hr is 60-70% and temperature varies more night to day. It is a bright space and I've bloomed Oncidiums and Den phals there too.

I've read they like to be a little cooler with a swing in temps but also I 've read varying amounts of light. Please steer me in the right direction.
