It can take up to 3 weeks to show sex, but more common is 2 weeks.

The plant measures the time of uninteruppted darkness which realises the flowering hormone, so make sure there are no light leaks.

and do what GaGrown said about 12/12. Once your into flowering, you can give them 14 dark and 10 light, but id wait untill 4 weeks into flowering.
LIP Reviewed by LIP on . No sex yet?! Well its been about a week now since i started force flowering and all is going well as far as plant growth but it hasnt showed any sex yet. If i remember correctly it takes only a couple days for it to show its sex right? Ive been doing over 12 hours of darkness a day and usually around 8 hours of sunlight daily. I was told that more darkness and less light was ok so thats waht ive been doing. Am i wrong about sexing only taking a few days? Could something else be the problem or does all sound Rating: 5
