That's incorrect, SOG is the most efficient way to increase yields per sq. ft per the least amount of time . Nothing else comes even close..... when I was running true SOG I'd easily get 2 oz per sq ft .Just a loss of size of flower and total yield
Loss of flower from side branches but done properly nothing but big top colas. At least from my experience. More weight per crop.No loss for smells and smoke. Just a loss of size of flower and total yield. A packed room of only dense tops or a room with big plants that have smaller lower buds. Then you add in the time it can save, by having less veg time. You can throw in another crop. You have less time to develop problems if you're going to have them. And the trimming is minimal.
