I wasn't trying to be an ahole or shit on you. You came talking unrealistic expectations and then tried to stick to it. If you harvesrt more then an actual confirmed half pound of bud I will eat an entire 7 gal pot of my soil. Now if you came asking, because of course it is your second grow, and truly wanted educated opinion on your yield then my original response would of been much different.
My tip to you is focus on getting the basics of growing down, then focus on quality, then focus on yield if you want. But with an , " I am on my second grow and I know I can pull 90 ounces in a 6x5 grow", ( I dont even care your light or strain, or method), then you obviously have no idea wtf you are talking about.
Wanna get the best yield with the set up and genetics you have?
Spend less time acting like a know it all, and much more time reading the great information available on here. Oh, and there are some nice and friendly folks who know what they are talking about too. Just ask ad I am sure there are many willing to help ya.
Get 90z from 6x5 out of your head.
Cheers
