Unless there's going to be a plant soil that I don't have to replace every year? But most of them release so many nutrients and play with water chemistry, so I'd be super scared of using it.
Otherwise I have better top soil and play sand at home (thanks to my tortoise). But then I would be scared of sand going down to the top soil layer when planting plants. But thicker cap I guess.
