8 plants, two ready to flower...only one room

So I've got two plants that are about 3 weeks ahead of the others. They are getting big and need to be put into the flower cycle. The other 6 need those extra 3 weeks of veg or they aren't going to yield much. Can't I just move the 2 that are ready out of the grow room at like 7:30 in the evening and put them back in at 7:30 in the morning. I would be moving them to a closet with total darkness. I could just do that for the 3 weeks and then switch the grow room to 12/12 and they would all be flowering? Bad idea?

moving the plants will work fine.

I f your faithful for those 3 weeks then yes it can be done. The only problem I see with that is forgetting to move them at the right time.As long as you dont miss your time by more than half hour to hour I think it'll be alright. SO DONT FORGET lol.Nobody like hermies...
