We try to take the outdoor harvest in two or three cuttings. First cut of harvest is the cola and all top buds, panel leaves and dying leaves are dropped to allow light inside of plant. Second cut gets the secondary growth under the colas. Last cut if I go three is the balance. Yesterday I did the final cutting on three Northern Lights and pulled an additional 13 oz. wet.
You don't have to harvest all at once, just be selective about where you cut from and the plant will continue to produceand mature.
