Soil Recipe

4 cups soil
4 cups peat moss
2 cups vermiculite
6 teaspoons agriculture lime (powdered calcium carbonate)

"4 cups of soil" is meaningless, of what does this soil consist, floor
sweeping?
There is no reason to steriliz vermiculite and lime, probably not peat moss
either.

I think it's retarded to sterilize potting soil oneself when it can be
readily purchased at mere pennies more than nonsterilized... there is no way
one can bake dirt in their home oven for less money than the branded
potting soil companies can process theirs by the freight car load, it's not
possible to ignore the economies of scale. And once a plant is potted the
soil is no longer sterile anymore anyway, in fact as soon as you handle that
cooked dirt it's no longer sterile. As far as insects, they will probably
seek out sterile soil quicker than nonsterile. It's really not necessary
for potting dirt to be sterile... actually it's just a marketing gimmick..
plants grow outdoors just fine in ordinary everyday dirty dirt.
