Sometimes, you might not be able to find the cross but you might should look up the parents. This should give you a look on the growth habits and what the plant needs.

Oncids. very bright some direct in a slat basket with some coco husk fiber no regular mix , they do well mounted . Hope this helps a little I am not an expert with them .. Gin
I agree with Gin. My barkerias grow mounted high in the greenhouse with daily watering during the summer. They grow like weeds and are starting to spike out right now....
