4 oz per plant isn’t impossible. I got just over that my last grow.Cheers @Glookies1 good to hear that from someone experienced with glookies for sure! To reach my goal I'm aiming for 4oz a plant hahah! Impossible but we will see what we get.
That said, I veg mine up pretty big before flowering.
I also find yield is more a factor of grow size than plant count. A 4x4 area will yeild about the same with 8 small plants as with 4 big ones.
