Laelia Speciosa Advice Needed

[escualida]

Hi all,

I’m about to receive a flask of Laelia Speciosa seedlings and I’m extremely excited about it but wanted to make sure I give them the best care possible. I’m finding it difficult to find consistent information online so I’m hoping you all can help me out.

This might be a dumb question but, is this plant considered rupicolous?

What would be the best medium to use straight out of the flask?

I have a covered growing tray that I can put them in, is this sufficient?

Any other advice for how to make sure they survive would be amazing. Thank you in advance!
