Is it possible, or easy, to over-water the gritty mix?
From what I understand, it's very difficult to over water this mix. I see water running out the bottom of the container (about 20-gallon) within seconds after I turned on the spray nozzle. Knowing that I need to have the Turface particles soaked, I kept the nozzle on for at least 5 minutes. When is the gritty mix considered to be "dry" and needs watering again? Is it when the top 1-2 inches are dry, or deeper that that?
