what you are saying about M-G soil is not what the best growers in the world say about it, from what they say miracle grow does not make the finest grow but will work. but not recommended for great strains or seeds for the most potential product. like i said dose your smoke win cannabis cups grown in M-G soil... NO because its not the best, but it works. look up danny dankos soil mix.
it is awesome, and is not fox farm. you have to mix a costly amount of organic additions compiled to have the best ORGANIC grow.

A. good seeds
B. good grow medium
C. good light
D. good grower

now hydro i disagree with but that's just me, the taste and favor and quality is forced and is not natural. you can have a fillet steak but organic fillets are better tasting. same as with cannabis the more organic you keep it wont make supper yields but super quality so it depends, do you want pounds of ok smoke or a smaller amount of great smoke. its up to you really.:thumbsup:
