i was wondering about how long it usually takes to show signs of flowering from when you switch light to 12/12
Hello Sonoma...
Males usually show their sex in 7 days and females usually show their sex in 14 days.
It is important that you don't have any light leaks and that the plants get 12 hours of uninterupted darkness every 24 hours..
yea as of right now i believe there all females they were clones and heave been showing female signs for a while i switched the light on the 15th so its been about 8 days and i have them in a homemade 5ftx5ft hydrohut thing with lots of ventilation would turning the regular room light on for say 1 min a day cause problems?Quote:

During the 12/12 phase, every stray lumen lessens yield. If there's light brighter than a full moon, it'll retard flowering if not stop it altogether.
Once the 12/12 cycle starts, it can take anywhere from 1 day to 3 weeks to show sex, depending on strain & conditions. Usually about a week for males, and by 2 weeks the females. But this is NOT a hard & fast rule. I've had girls show before boys often enough to know that time into 12/12 is no indicator.
well said VOLKER!!! :)
