What is a good soil for Mothers

I am new to the Mother thing. I have some clones in a "Bubble Cloner" that I got from a buddy. They are ready to go into soil but and not really sure what to use.
I would use FFOF but want to stay away from the hyrdo store as much as I can.
Was going to get some Miracle-Gro Organic but was not sure. Have read bad things about MG soil and Mary Jane, but really do not remember reading anything about the Organic. If I were to use the MG Org. Does it need anything added (Lime, Perlite etc..)?

What is everyone using?

My favorite mix:

50% organic compost (mine)
25% organic worm castings (from the bottom of the compost pile)
15% coarse sand
10% perlite
