bending is the best option... by bending your plant, you allow more light to reach the lower areas of the plant where bud development would normally be scant/weak.. your secondary growth will branch upward away from the main stem and be more uniformly exposed to the light... it will leave you with several small main colas, and when done properly will increase potency and yield

side note: i always induce flowering early.. usually around 2 or 3 weeks to keep hieght under control
