When I flush i run about 120 mins of water on my greens in pulse cycles so i do not waste too much with surface run off. We are fortunate enough to have one day a week when we are closed so it is not too difficult. We do this kind of flush once a year just to give the greens a "clean out" (and our sodium is not horrible 120ppm). Our normal irrigation practices for maintenance are a heavy watering 25-40 mins every 7-12 days depending on the weather, we just hand water in between (one or two guys can get all the greens daily here due to being private).
I normally deep tine greens every month to a depth of 10 inches with a soil reliever, i try to do this a day or two before a flush. I might apply gypsum or granular potassium at the same time also.
In the summer i will vent the greens in conjunction with a deep tine by just alternating the two (pro core 648 and soil reliever) as the plant needs more oxygen. If we are getting any black layer in exits points we will hand tine these areas and apply granular potassium.
I have attached a photo to show some roots coming out of the cup cutter. I have not measured them but the look good.
Cheers
