GL...let me dig up a few old photos and post them....you are right....there are HUGE MASSES of roots jammed into that red bucket and that's what is causing your rootbound issues. I'm WAY afraid to make guesses on yield because your plants could start to crash and burn at any time......especially with root issues. Believe me without healthy roots and a good enviroment for them there's no guarantees to finish and Mr Hound and I have seen them go downhill FAST firsthand.
