Its funny...i actually make mistakes every round.
But hey, get it mostly right and do alright!! Thats pretty much what i am trying to do...despite the small space (16"deep X 56" long X 28" from the top of the pots to the lights surface) i am running 8 different plants/strains. For the most part root restriction has been working great, so far only one plant refused to listen to my plan...i suspect other giant auto strains would refuse to follow my plan as well!!
You could do very, very well with a double stacked closet and small framed autos in tight quarters in smaller pots.
