If you start growing outside now... The daylight hours will be decreasing until Dec 21st... 12/12 will be the aprox daylight.. Then the daylight hours per day will start to increase one/two min per day until June 21st or so with aprox a 16/8 daylight schedule..

IMO if you can get the girls to finish before Feb 1st or so I think you will be ok... I've never done what your trying to do outdoors.. Indoors I have..

BTW this technique dose not produce large yields... It's like doing 12/12 from a seed indoors.. Works just fine, but just not for large yields.. :thumbsup:
