Ikea decorative rocks in potting mix?
I've been shopping around for materials to use in my potting mix 2.0, I've had a hard time finding pumice and turface, today I came across these decorative small rocks from IKEA, I know there are probably dyed so I'll give it thorough wash before using them. But are these the appropriate size? I've seen pictures of people's mix and these look similar to granite grit and pumice. I would probably get rid of the bigger chunks.
What about these crushed glass pieces? Again I know they're used as top dressings, but would they be usable as mix too to help drainage? They are much finer than the rocks.
