Switching to 12/12

What's the average time that it takes for a plant to start flowering once the light is turned to 12/12?

can take up to two weeks my current took 12 days to show sex

Anywhere from 10 - 20 days to see noticeable changes in you ladies.

regards,

I veg 24/0. When I switch to 12/12 I will see the first set of white hairs in 6-7 days. When I used to veg for 18/6, then switched to 12/12 it took between 10-20 days to see the first set of white hairs. I will always veg 24/0 now, seems the plants grow much faster and things happen much faster when you switch to 12/12.

I wonder about your root development though...Sure the plant is growing fast at the top, but whats going on inside of the container?

usally 1-2 weeks they start flowering but I'm sure a sativa dominent plant will take a bit longer to start but I never actually grown a long flowering plant though.
