Scotts does not contain miracle grow. At least not Scotts regular potting soil.

I prefer the PRO MIX....it does have enuff nutrients in to feed a baby for 4 weeks...no doubts.

It is very airy and very pourous...Scotts is damn good soil too.

This grow was 50% PRO MIX - 50% Scotts potting soil blended together with lava rocks at the base.
