Inducing flowering outdoors-Kens Blue Dream

I want to flower two of these girls by putting them in a dark room for twelve hours and taking them outside for 12. They are currently in 7 gallon pots and have been vegging for at least a month and a half. They are in ocean forest and just starting giving their first foxfarms trio feeding. I dont know if I should transplant them into bigger pots with nutrient-free medium and adding the flowering nutes. Or are 7 gallons enough?? Or does anybody have any suggestions ?? Im planning on doing a journal as soon as I begin. - Thanks

Yes I am aware. I might just cover them up for a few hours in the evening and uncover them at night when dark. Will have to keep track of the sunrise to get them exactly the 12 hours of darkness. Itll be hard work , but im willing to accept the challenge.
