Dendrobium kingianum winter care

[PuiPuiMolcar]

Southern CA here, my area dropped to 40 consistently these past days it doesnt seem to care at all. I let it in the full sun for about 2-3 hours then get dappled lights from the trees. In fact one of them bloomed last week.
I think most my Aussie Den can handle the cold better than the heat ironically.
