im not sayin dont use it,its horrible..im just sayin be damn careful usin it,its a harsh fert. i grew with it for 5 yrs outdoors with no problems,but i was aware from the get go about how harsh it is and i was just always very careful w/ it.
i just believe in spending a little money on some good nutes like fox farm,ionic,etc. rather than a cheap bottle of miracle grow.as for usin the outdoors dirt indoors,be on the look out for bugs,this is the reason why i dont grow indoors with soil from the earth.
as for taste,you definitly need to give it a good flush,otherwise you'll taste the nasyness in your final product
if im buyin from a grower that uses miracle grow,i always test it b-4 buying it due to that nasty taste.
