While it’s not labeled as organic, it’s mostly peat and what I’m used to. I have used the Coir (HP-CC) in the past but the peat seems to have worked pretty good so far.
And, I have six bails of the stuff.
It is an interesting point though that I should consider. I have mixed in worm castings to increase the organic ‘complexity’ with good results but it seems mostly anecdotal to me so far. Might try a thing or two.
