as Kieahtoka said it described the possible yield one can hope to achieve in the sea of green.the problem is people use different ways of SOG and the overall yield will depend of the number of different factors of course.
but Xg/m2 may mean also that the plant living up to her flowering potential should give Xg of buds ofevery m2 of space it takes.so to me it seems that one or two big mature sativa mums should give the same yield as, let say, 100 tiny plants in SOG. |
