Gravel and Soil .. Which on top ?

[sumsum80]

I am curretly using black quautz gravel. But because i want to have some hair Grass at my foreground, I dun tink my gravel can grow.

Thus I am adding some GEX soil on top of my fore ground gravel. Is it recommeded ?

I don't see why it cannot be done but we usually use either gravel or soil, we don't mix them. Alternatively, you can consider adding root tabs (substrate fertilizer) in the form of tablets/capsules/sticks to fertilized your existing gravel.
