My tale was of misery also. I put my fav Paph in s/h and it did nothing. I got round to having a look in the pot and many roots had rotted.
A repot back into bark and luckily is recovered fast and is now in spike
I believe I may have kept it too wet, which is a problem I have due to my growing conditions. I have used them as potting media and not used the water reservoir, but I find they need watering too often.
