Watering twice daily vs. once daily with Roots Original

[AppleFritter]

What is the consensus regarding these routines? Is it better for a plant to get a more frequent watering, say once every 12 hours, or is it better to have one long wet period 24 hours? I am not watering to run off

Plant will drink as much as she wants.
Think hydro, no wet-dry cycle.

So the medium is to stay moist, with roots original?
