I have been using this mix for all my Paph's.My paph's really like this mix.I still do add garden lime as a top dressing.This mix is very fine and it has some type of wetting agent in it (little yellow balls).I have not use this with any of my phal.I really need to repot a couple of phal. into this mix.All of my other chids are doing well except for my phal.The rest of the chids are in Med.Size Bark Mix by Better-Gro. Take Care,Rich
