Mom randomly bought me orchids at a supermarket

People run into trouble with these when they don't water enough, or when temperatures are too high.

None is happy when it gets much over 35C, and those with cool-growing ancestors may not like being over 30C. Remember that direct sun heats them, so if air circulation isn't strong, they may get too hot even if air temperature should be fine.

Edit: European members have written that these Oncidium intergeneric hybrids have been called "Cambrias" in the past.

You could buy identical plants going by either Cambria or Odontoglossum, so yeah, that one is true.

Ventilation is hardly ever a problem; while not too windy, there's always a breeze from one or another direction. I kept checking the leaves over the two month period my Brassia are out and they only ever get warmer right at the end of the sunlight hours (just mildly, not hot). Due to the shape and size of the overhang, the amount of direct sun the spot gets increases with the onset of winter (traveling lower in the sky). And judging by the sheer amount of growth happening, I have a strong suspicion they very much enjoy it.

Winter light is precious! The orchids do love it. Many have ancestors that came from monsoonal climates that are overcast and wet in summer, with diminished rain - which means less cloud cover therefore brighter. That winter brightness is often hard to achieve in the cold, rainy northern latitudes - you are in a great location!

They are really pretty! How very nice of your mother to brighten your day with some beautiful orchids!

I am actually surprised how much direct sun can some of them take, even when it's not propely cold outside. SO much so that certain rather tropical plants get to live here, outside, without much of an issue. The Brassia seem to like more of it than my young coffee plant.

It is, but now there's a forth. It's spiraling.
