i have completed about 6 scrogs and a few traditional grows. you definetely get better each time especially scrog training. each strain responds differently to scrog as well, so you have to learn each strain to get the best yeild. expert scrogger's boast 2.4oz per square foot of screen!. i am starting to get the hang of my ww's (i think)for scrog at least. i have alot more to learn in all aspects of growing. i started growing last year so i don't quite have a full year yet. i have 4 chambers (3 flower / 1 veg) up and running so i get alot of experience pretty quickly. i also spent alot of time on the old farts thread at og and those guys really know their shit!!!
