They will continue to grow, but if no one can see you are growing weed right now, I don't think they will notice during flower either.
If you are worried about the height being a security factor, cut them back.
How much sun do they get?


well at the moment school is on holiday so not many people around there,but they go back in 4 weeks though like i say it may not be noticable if your not looking for it,and surely the pumpkins hanging in front of my window is gonna attract attention away

the garden is south facing so they have about an hour shade in the morning and evening,no idea what time the sun comes up cos i'm sleeping but it's down before 9pm
