topping is an excellent weigh to control height and increase yield. i'd recommend topping to produce 4 main colas, head over to the advanced cultivation forum and check out uncle ben's guides - they'll explain all
Is topping a good idea to keep plants shorter? or will this stun them to much? should I just let them grow their own way?
