The only greensand I am familiar with is used for casting (as in molten 
metal casting). It's very fine and packs together, and I don't think it 
would make a very good substrate. I suggest you get a sample and see what 
you think of it before using it. If it is very fine and packs together than 
a substrate made with it would gradually pack into a solid mass that plants 
would not be able to easily root into.
