I have tried a commercial pottery clay called Terrastone pottery clay
Here's a little more info. There's a link on my website with the current
URL if the one below doesn't work.
20 Kg Terrastone iron rich pottery clay
Cost: ~$18 Cdn for 20 Kg
Address: Plainsman Clays Ltd Phone: (403)527-8535

There have also been several people using red A.R.T. clay in the USA and
I have some information on it:
Redart 200 Mesh.
A low fire terra cotta clay from Ohio, but clean burning due to
geological formation of the deposit. Good color but poor plasticity.
It is available in dry form only.
25# $ 9.00
A.R.T.'s minimum order policy is $50.00, smaller orders incur a $10.00
handling charge. There is a link on my website with the current URL.
These clays were chose because of their high iron content. These clays
are all extremely fine in texture and so you could probably mix them
with sand (dry form is easiest for this) and a little will go a long
way. I suggest you keep it in the bottom 1/3 of the substrate like any
clay, so that you minimize the amount that gets drawn up into the water
if you uproot a plant.
