[MetroMix 360]

I might be able to answer that. I have a bag of
Sun Gro LG-3 here, and on the back it lists the
composition of a bunch of their seed-starting
and container mixes. It does not mention "MetroMix",
but there is a "360":

35-45% composted pine bark, composted peanut hulls,
Canadian sphagnum peat moss, perlite, vermiculite,
dolomite lime (for pH adjustment), gypsum, wetting agent.

If the mix is labelled "Organic", the wetting agent would be
yucca extract.

(For reference, the LG-3 is: 70-80% Canadian sphagnum
peat moss, vermiculite, dolomite lime, gypsum, wetting
agent. I did not actually select it from among the several
Sun Gro mix formulations, I traded a landscaper/nurseryman
something for it, and that is what he had on hand for seed
starting.)
