Mounting Brassavola nodosa 'little stars'; culture advice please

[DTEguy]

The plants came in from OrchidsAmore today. Got the buy 2 get one free deal. Was going to give the other one for a friend recovering from Chemo to cheer her up. All three were supposed to be from 4 inch pots but but one was much smaller with only less than 2 inches roots; with remnant of old sphagnum moss in the roots while the 2 other has barks.

They insisted that it was from a 4 inch pot. They should have advertised buy 2 get 0.5 instead
