Did they not use the Chelated Micronutrient Mix made by Plant Products
of Brampton, Ontario?

There is a fellow, Shiao Y. Wang  of the University of Southern
Mississippi who mixes up his own mix. He posted its compostion to
this mailing list about two years ago.

I purchased three MH setups from them last year. One of the reasons that
I went with the 4000K lamps was the "below cost pricing" of their 5500K
lamps. I had trouble believing them to be the real McCoy. You got lucky
Steve. Actually $65 is still cheap. These fellows aren't Coralife.
They're nice guys just trying to make a living, not create an empire.
