i have a plant thats about 2 weeks old and i am switching to 12/12 to hurry up and see sex cus my last 2 plants were males, how long does it take for such a young plant to start showing sex, and could you tell me any miscellaneous information that i should know about 12/12.

thanks for the help

Yes. What kind of lights are we talking, CFL's or are you going from MH to HPS or CFL to HPS? Either way, yeah, you want to put more 2700 in there. You can keep the others tho, just make sure you have more 2700 that the others...

it really depends on the genetics and how you have cared for it. i grow with a short veg period to speed up the process and it usually cuts the yield down about 1/2. but this really depends on the strain

yeah, don't start your flower counting until after females show sex. ie, they'll force flower, but even though they're in 12/12, the actual flower time doesn't start until the plants are actually flowering.
