Small mounted orchids
 

Hello everyone!
Apart from two phalaenopsis that I've had for a long time, I'm a beginner in the ochridae world.
I've just acquired two small orchids mounted on cork, a "Vandoglossum Furuse" and an "Angraecum Didieri".
I'd like to know how to water them. So far, I've sprayed them daily, but should I also bathe them?
And every two or three weeks, I'm away for 2 or 3 days. Is this a problem?
The humidity in my apartment always varies between 45 and 50%.

First, Welcome!

I think that the daily spraying (a good soaking, not just a spritz) will be fine. If you are away for a few days, perhaps the soak will be helpful to give them a bit of extra reserve. If the weather is warm during those times when you're away for a few days, you can also increase the "local" humidity by putting a plastic bag (open at the bottom) over them after the soaking.

Hi Roberta,
Thanks a lot for your recommendations!
I’m a bit concern because since I got them, I think they are getting a bit yellowish/brown at the tip of some of their leaves. Do you think they’re are healthy?

I find mounted orchids impossible to keep in my home. They dry out too fast. I would suggest watering by putting each into a bowl of water for 1-2 hours per day. A 2-3 day absence on a regular basis may or may not be a problem. I would consider keeping them in a jar or terrarium during the absences, and they would probably prefer that most of the time.
