This topic has been very helpful and very timely! My paph (a sukhakuli hybrid) looks like it's coming down with root rot. It's in 100% coconut shell mix, but seems to hold water too long (I water about every 10 days), especially in my house where the temp range is 50º-60º. I'm guessing a mixture that dries out quicker will help the situation. Then again, maybe it's just too cold and dampness of the coconut bark just makes it worse.
Can anyone suggest which of the mixes already mentioned would work best to prevent the rot? Or recommend a recipe that might help?
Thanks for any advice. (And my paph thanks you too!)
