Using suckit bucket. Getting 2-3 inch a day growth rates. Using advanced nutrients sensi grow a and b fed conventionally. I am also using a "Romaurie effect"control res, so I just add the nutes and they mix into system in 24 hours. There is special technology at work here, and roots are in pure air once autosyphon breaks. This vacuum driven aeration allows fast growth rates but "Suckit Buckets" are hard to make and calibrate.
