in a 2x2 scrog you could have a max yeild of 9.6 oz if you go by the 2.4 oz per square foot that expert scroggers boast. i had a 2x2 scrog but the most i could manage was about 5.5oz. i have no experience with v or vertical scrog personally but i have seen a few vertical scrogs that looked amazing. i am gonna try to find some of the info i've seen on vertical scrog and i'll post a link here if i can find it.
