Question of the Week

Hello. I had considered taking the MG program years ago but was told you folks advocate the use of Miracle Gro and other synthetic chemicals. I'm wondering whether or not this is true? Unless the MG practice is one of a strictly organic approach, I won't bother; but if the rumor is false, and you folks are recommending no chemicals, I'd love to sign up.
