best growing rocks

What are the best growing rocks to use. Ten years ago I used to use pea gravel because it was cheap.

I have used several kinds with no noticeable different growing results.
I like the light weight kind as opposed to the heavier stuff.
I have never tried pea gravel because I'm not sure it holds enough oxygen to handle all the abuse I can give a plant..
