i have some seedlings going, but i cant put them outside fulltime yet because i dont want them to flower too early. what is the absolute minimum amount of light plants can receive and not flower? i know they usually flower with a photoperiod of 12/12, so will a photo period of 12.5/11.5 or 13/11 be sufficient to keep the vegging? this is my first grow, so any and all advice would be appreciated
