Clay substrate around Greensboro?
It's a long shot, but does anybody happen to know of a place that sells Turface, Diamond-Pro, or any other baked clay soil in the Greensboro area? There's a John Deere out a ways that might sell Turface, but I'm looking for more options. Steering clear of Oil-Dri, and I'd rather have a high-CEC cheap substrate than simple pool filter sand.
Yes, I know, I could buy Flourite, but a 50lb bag of Turface for $8 beats out a 15lb bag of Flourite for $18 any day. And I'll probably need 120+lbs to fill out a 90g.
