I still put EVERY phal in this media and they all seem to LOVE it!
I will add one word of caution that i have noted from using it for several years now. If you purchase a large "brick" and break off portions over time for use you MAY find that the brick is not evenly mixed - in terms of the quality of the contained material - I have noted some bricks contain portions of very fine material almost like dust/powder (that can excessively compact if not mixed with other coir/materials) and then at the other extreme sections may be quite airy/springy - almost like wooden steel wool. It appears that the best option might (?) be to break up and rehydrate the entire block/brick at once and mix with your other materials and keep stored for later use. I have yet to do this - but it seems like a good idea. I currently have a few plants (out of 60 or so) that have quite heavy/compacted media bases - doesn't seem to hurt the plants a bit - just can't water them but about every 2-4 weeks during the cool part of the year!
I may get ambitious one of these days and redo a few to even them out with the rest?
Another important thing in my book is placing a good healthy portion of styrofoam peanuts in the bottom of the pot - especially if the plant is large and the pot is a good sized one. I just repotted my largest phal a couple months ago - back into coir - back into the same 8 inch pot - and there is about two inches of peanuts in the bottom - the huge mass of roots looked fabulous!
