Black D.O.G Humboldt seed

Last week of growing. I can't let them grow too much since my box is 80x80 only. I moved them in the final recipient (11l) I broke the roots of 1 plant so it remained in the 2,5l recipient... I will move it in a 6,5l instead of a 11l to see the difference...so far I am wondering if it's good 11l or if it's too big for my box. Next week, I will change the light schedule to 12/12 Topping on all plants. Except the small one remaining in the small recipient
