    Kinda like a root tab: Red clay? Any others anyone may know of?

    I also use those too, but I was more or less asking for very iron-rich additives...like Red Mexican clay...or something better or equal to that!

    ADA Amazonia Soil is pretty rich in Fe. If you asked in terms of root tabs; ADA Iron Bottom Plus.
