Bulbophyllum phaleonopsis minimum temperature?

[Katcrow]

Hello all, this is my very first post on this forum. I've been serious about orchids for about a year now. I just acquired a bulbophyllum phaleonopsis and it is the most expensive plant I have ever purchased, so while I am very excited I am also being extra cautious!

My question is, especially to people who live in a similar climate to me (South Florida East coast, zone 10A), what temperature do you bring it inside? Right now it's about 60° F at night (sometimes less it's supposed to go down to 48 soon) I brought it inside under a grow light, it's at 55% humidity and 77° inside. Once it gets warmer I will of course put it out on my patio and it will be perfect for it but in the meantime, am I doing the right thing? The longest leaf is about 13 inches and it's in a 4 inch pot. Any tips or advice is super appreciated!
