Time it takes to flower

How long after you switch the lights to 12/12 does it take for the plant to flower?

6 to 14 weeks. Indica 6 to 8 weeks. Savativas is much longer.

8 weeks give or take 2-4 weeks.. it really depends on what strain you grow.. thats not including 2-4 weeks to dry and cure After harvest!! be prepared for the long haul!!
