Hey,

I suggested MG cause its always available at any store and I was trying to keep it simple since the poster seemd new. It may not be the absolute ideal for MG growth, but I have had great results with MG and every other indoor plant mix that I have ever tried and I always mix with perlite to lighten it up a bit.

Maybe I do something different, but I don't really get much different results from one indoor mix to another as long as it is light enough to drain.
