I just got my free copy of the Dr. Earth magazine in the mail! I couldn't believe how interesting and technical it is, while still being readable by little ole' plebian me. Very cool! Admittedly, they have their entire catalog in the the magazine too, but it's just a few pages, and honestly they look like high quality gardening products.
