24 hr veg

I started five spacebombs from seed and have kept them under 24 hr T5. They have been veging for about 5 weeks and suprizingly have preflowered all 5 are fem (thanks subcool) any way I want to move them outdoors in the next few weeks I was just wondering if the 18 hr outdoor cycle will cuase them to flower being that they have never seen darkness before. Does anybody have experience with this

24 to 18 should not make them flower unless they are semi auto or autos...............peace...I veg my shit on 24 hours and i just tell people it is because i am to lazy to get another timer ....
