I think that you have a pretty proficient method IMO, not all fancy, but rather simple, I like it and seems a fair enough way to keep plant counts down without having to do a SCROG, whitch are still a very good method, just time consuming IMO. Have you tried any other strains and had similar success?
I am about to set up another room, 2K and I may mess around with something like this, except I think that if I have the extra change around I will do 3 40 gallon tubs with 4 plants each, giving me a total of 3 tubs and 12 plants using a top feed drip system. I think with that I could probably veg for 3 weeks to a month and get the same growth as 2 months veg in soil, but I am not sure if they would bush out too much for 4 to be in one 4 by 2 40 gallon tub.
Well, keep up the good work.
