Would CHC's work better long term than pine bark fines? I have a few tropical fruit tree's that I am getting ready to pot up and was thinking of using 1/3 CHC, 1/3 turface, and 1/3 jungle growth potting mix. Seems like it would last longer with the CHC's rather that the fines to me. Can you think of any negatives to this or any suggested improvements? Also, what size CHC would be best?
