Unfortunately, I did not get the plant repotted today. Had something else come up. Maybe it's a good thing, having read these messages now. I have some Pro Mix and I have some orchid mix. I'll mix the two together.
I have been very careful with watering so I am fairly sure it does not have root rot. Because it was totally in orchid mix, I would sink the pot for about three minutes and then drain it. I did that every seven to 10 days, depending on how hot it was. Right now, the house is at 68° but as it gets colder outside I will be turning the heat up to around 72°. Is that warm enough for house plants? Is it hot enough for this plant? I have a room heater if one is required.
Thank you both!
