suga is used to sweeten flowers not make them yeild more ... Man growers not just cannabis have been using suga for years to enhance there flavors both taste and smells
Use molassis or sucanat (organic sugar cane extract) no regular sugar the sucanat retains its molassis where as regualr sugar doesn't its used to sweeten but its carbs for them so they will swell a bit atleast mine have just started using sucanat
Molasses, Molasses!!, since i have been using unsulphured molasses, my buds have swelled twice as big as my firts grow. I noticed a huge difference for me. I use 2-3 tbs per gallon , my plants are 3 1/2 feet week 8 flowering, 3 feedings in 9 days with molasses my buds swelled alot and i can actually smell i ton the bud a little.
