well, just think about what it is that you are incrementally flushing out of there... microbes, minerals, nutrients, and then of course the carbon and salts. I water to runoff, and then I quit. I do come in hours later and water to runoff again, just to see how much the plants used in that time... but, I try to be good enough and slow enough that when I see the drip of runoff starting, I quit, knowing that more will drop over time because of gravity. I doubt my runoff is ever more than 1% because I don't like leaving water in the drip trays, especially in flower when I am trying to get the RH down. In veg I am slightly less careful and maybe go to 2%, but it is only for the humidity and not to clean or flush anything.Although, as a soil grower, I am not entirely sure if having 10% to 20% run-off every time is even healthy for the soil and the plant.
