My goodness, Greene. I don't know a thing about Mel's Mix. I am sure it is just wonderful. I was responding, not about that particular mix but about the formula you gave for a "created" one. I just thought it was water-retentive. Forgive me, if I am in error. Perhaps it is a well-draining mix. The main thing is that we all need a lot more information from the original poster to really give applicable advice.
