This soil any good for super soil mix?

i was thinkin about grabbin some of this stuff from my local store its fairly cheap for quite a bit and looks to be of a better mix than mg or ff which is really all else i can find that seems suitable even in the slightest to me.

I found a local garden center and they sell 1.5 cf bags of their home made aeration mix for $3.50 and it is basically the same thing you got there. Check the yellowpages I am sure there is something near you.
