I was flooding three times a day, I still have a lot less issues using larger tubing instead of the 1/2 inch it comes with, upsized to three quarter inch and had a lot less problem, The real trick is keeping the tubes clean and getting the real clean after every run,
I do not know if flooding more frequently would keep the roots from stretching as much,
the bottom of my buckets by the end of a run are full of roots, you will see a line of tubes in the picture and t fitting at the back of the hose run that is clipped to the last bucket in the line, that is for a garden hose clean out, also a garden hose fits into 3/4 inch tube a lot better than half inch tubing to it does not spray water all over you and in your face when you clean them out, it saves a lot of time taking the fittings apart and putting them back together
