Oncidium temperatures

[Paul Mc]

OK, so I'm wondering what temperature ranges are best for oncidiums. I know that it really depends upon the kind you have, so here's my list.

Colmanara (Miltonia x Oncidium x Ondontoglossum)
Sharry Baby 'Sweet Frangrance' AM-AOS
Sphacelatum
DGMRA Winter Wonderland
Gdlra Tahitian Dancer
Mtssa CM Fitch Izumi

I guess I'm wondering because a previous post was about the Mtssa CM Fitch Izumi doing something strange that didn't resemble under/over watering or fertilization as I understand it. As of this morning, the temperatures were 68 degrees when I woke up and the plant is looking a bit more damaged. I am starting to wonder if it's not temperature damage. Perhaps it's time to at least pull the Mtssa CM Fitch Izumi indoors and leave the rest out as they appear to be loving the temperature changes.

Daytime temps are still in the upper 80's by the way, although I understand they are supposed to be in the 70's for two days and then back into the 80's.
