Name: Michele Roth N.E. Indiana - Zone 5b, and F (Zone 9b) I'm always on my way out the door..
I don't know anything more about SunGro, not really. I just googled Sunshine Mix and that's what came up. What's the company name that you buy from?
Sorry to be a pest, but I still need some mix for fooling around with in the GH after frost sets in, and to have some on hand for an early start next Spring. I can't seem to get enough of playing in the dirt!
