Love seeing your "phal hospital". I have one of my own with 8 patients 7 of which are from "big Box" stores that were ready to throw them out. It has really been fun and interesting to bring them back to life. Right now, only one is in intensive care and could be terminal. The other 7 all have formed new leaves and seem healthy, even though they have shed some of the leaves they had when I purchased them. Why do you have plastic wrap on them? For humidity? Haven't tried that.
