Thank you guys!
What i endup doing was moving the really big ones indide. I set up a nice fall room with 1000W high preassure sodium and got them on 12-12. i just hope they did not start to revert already haha but they look like they are still flowering. I left the small ones outside to let the nateure take it's course, will see...
Do you think i did the right thing or no? i want to minimize the risk of herms and i will have some outdoor projects going on, so i can't allowe to have any herms around. So i was thinking to just flower what i can, have some resoults in two months and in the worse case i will not have any budding females around yet.
