All that's in it is the paph 'Ninja' I picked up during my visit with him, but I intend to pot up some bareroot phals that will be arriving shortly with it, see how they do. His phals were a little on the rough side, but I think it had more to do with the amount of light they were getting, not the mix.
since it's primarily CHC, I suppose I would put it somewhere between medium bark on the dry end and a sphag/bark mix on the wet end, but folks here with more experience are probably better at providing an accurate analogy.
it's been here only a short time, but the Ninja appears to be doing ok; 3" aircone, Frank's mix, I'm watering every fourth day or so.
also, you have a pm.
