I've only used LR, but even then I've waited 6 months or so for corals. Like I've seen others say, get a couple easy softies that don't mind water that isn't perfect and they will help seed the tank. I've thrown in a xenia colony as they seem to grow like wildfire even in newer tanks.
Even with dry rock, you can add some softies after a few months, but just know that you'll be dealing with the algae phases while trying to enjoy your tank. That parts takes at least a year to stabilize (ish).
