New terrarium

[Aratz]

Hello, this is the first post that I put in this forum.
My experience with orchids is not very long! I have two hybrids of phalaenopsis and now I want to try to culture some orchids inside of my geosesarma's terrarium but I have several quentions.

My biggest problem is that, in summer, the temperature of the terrariun could go up to 95°. Anyway, I have one fan inside and I could put another one outside to move new air inside. The another problem is that the humidity is between 80-95%.

I think that Haraella retrocalla will grow in this conditions, but there are more orchids that will grow Ok there??

Do you think that the hygrolon will be a good substrate to grow this orchids?

Thank you very much!!
