Indoor grows is where the problems come in.
Outdoor MG nuts are great because of the outdoor soil.
When growing indoors MG tends to not drain out well but to me thats the growers fault.
If you dont overdue it (Miricale Grow is the #1 Misused Fert in the world)and have good drainage a good MG feeding then a drain feeding will work great on indoor grows.
I will say that this is the case for ANY nuts at all if you dont have good drainage and you just always add nuts and never flush them out with pure H2O then your soil will become acidic and kill your hard work.

As far as the soil it sucks I didnt know any better and I used it many many times when I started with much failure.
It is only after I started using other soils I became successful in grows I would say the MG soil was to blame as I do everything the same as I did when I started with a few tweaks as the years passed of course.
DFG
