right now i mix 2 parts long fibered sphagnum (not live) that i soak very well and tear up a bit, 1 part perlite, and 1 part ground coir that has been rehydrated.
in a pot for a new nep (like all my recent rescues) i put a thin layer of coir fiber in the bottom of the pot (to retain media and drain readily), on top of that i add a 1 inch layer of rehydrated LFS. and on top of that my potting mixture described before.
i mound it up and lay the roots around it in a cone shape, then pile more media on top and snug it down, then one more layer of wet LFS on top. then i pray.

Hi RLK and ever Dave
there is no magical cure , some times plants just will up and die for no good reason,even with ideal conditions.
I dont know about a Guru but I suppose I have more experience than most people, will leave it at that
Ok well after using some large amount of mixes over the years ,now all I use except for say 7 or 8 plants out of 400 ,is live sphagnum moss, I did a write up on its befits in the plant ID section you may want to read that .
Cori fibre and coco chips are or can be quite hazards to neps if the product comes from a island country where fresh water is not plentiful as they use sea or salt water to process the cocco chips and other coco products, and once re hydrated its salt ooses out making it poison to all plants or increasing the salt levels to seriously affect your plant , so know your product !! and I dont use it at all because you just dont know lableing is not all ways true !!been caught out already use a tts meter and try yours, you may be surprised !!
I am not keen on perlite as its volcanic and carries a lot of minerals that could be not so good for nep's all so if not washed and rinsed thoroughly as its a hassle to do so I dont bother !!, had some bad experiences with it and use it rarely, using bark , charcoal , peanut shells and other products are time consuming and can get expensive for the grade you need and usually hard to find , so the simple solution was strait live sphagnum moss in a pot , you can control the watering, it lets you know when it needs water and if condition are not right , it dies or dries out , use to much fertiliser on it it goes to slime or green mouldy gook !! you know, if its growing green lush and quickly in that pot humidity is right , your temp is good light is about right and you will see the nep growing as it should ! so for me there is no other mix to use !! but that is in my green house with controlled conditions, and may not suite every one as every one has there own climate and conditions to contend with . so really the mix is important yes most neps will grow in most mixes you give them but they need the right climate condition to grow well , so look up the conditions in Borneo,Malaysia or surrounding country's , either high land or low land plants ,which ever you are growing and try to get as close to that climate condition, as they are very different conditions between high and low land plants, and most of your problems will be gone !! one critical point is ventilation stale air or non movement of air in your green house will result in fungal and mould appearing ,so you need air flow just enough to have the leaves moving around like a light breeze ,especially when you need high humidity as well as you do
If you need any more info let me know !
