This is my experience using it for houseplants and plants I plan on bringing in for winters, including tropicals.

For me, it worked at first, the compacted within weeks, which made my plants sick...Even worst in the winter when it can take days to dry, it can breed a mnay fungus knats that are hard to rid of..

I also have root rot problems with my annuals when there is lots of rain in any givin period, starting right away..
If left to me to water, my annuals will do ok till summers end..

I have tried most of the MG mix's this year. Not impressed.

I think the Sta-Green from Lowes is a better product. And still use it in one of the Blends here, use with perlite and pine park or "coco hair".

just my two cents
