Hey all, I'm starting a 20 gallon planted tank and I'm going to plant grass from seeds into substrate before filling with water. I'm wondering if I should grow the grass and then place my dragon stone on top or can I place my rocks before the grass grows? Thanks, any help appreciated!

Most (all) aquarium plant seeds sold out there are false non-aquatic species. At best they are some Hygrophila sp. not fit for carpeting.
In general for dry start you want all your hardscape in place and secure. Putting large rocks on top of the substrate has the risk of them moving around and damaging the tank.
