I have often read about people using TMG or asking where they can buy some. Seeing I am running low on most of my fertilizers (Plant Gro, Flourish K, Flourish Trace) I'd like to know more about TMG from those who use it. I was thinking of using Flourish instead of Plant Gro when it runs out but would like to know if TMG is a better choice. Any suggestions? Giancarlo Podio
