Let me state some specific circumstances,
IF you go with The sea of green, done with this system, in a small confined space like the end of a closet, and having all 6 females very crowed in, (or 4) and you grow (veg) 2 weeks, then do 12/12 Bloom or budding for 8 weeks, you will have one big cola, (not the biggest you've ever seen, but banana size big) on top of each plant. Cut off, and dried for 4 days and cured for 4 weeks, you will get one big bud and 2 or 3 very small buds that weigh a dried 12 to 14 grams each.
So if you started with seed, got 4 fems out of 6, all grown tighly togehter, those 4 plants would give you 4 buds, almost 48 to 56 grams dried. Then you will still have about 60 pop corn fluff buds that you can harvest or continue to allow them to get bigger by putting the lights to them as heavy as you can. 4 fems done the way I described above, can give you 3 to 4 ounces of high grade bud and about 16 oz of female leaves or more.
I am going to yield much more than that but I am into my 5th month, instead of a normal 3 months.
