Here is a soil mix I used for one of my grows with good success.

you will need the following

1 bag of green sand ( http://www.garden.com/garden-articles/what-the-heck-is-greensand/128/ )

1 bag of composted cow manure ( http://www.vegetablegardener.com/item/2427/using-manure-to-fertilize-your-garden/page/all )

Note the link refers to cow manure in general, Composted manure is best in order to save time.

1 bag of peat moss ( http://www.peatmoss.com/pm-veg.php )

mix 1/2 bag gn sand with the composted cow manure and about 1/4 a bag of peat moss.

once mixed well test it by taking a hand full and compressing it. When you open your hand it should slowly fall apart.

You may add your own nutrients as you see fit.
