the problem is , its in a pc case yeah if i let it veg 12 inches when i put it to flower it can double the size so it wont fit in the case anymore , thats the problem
It should yeild more if veged for longer, but if space is the issue then you have no choice really. You can still pull some nice buds from smaller plants though. I too am doing 12/12 all the way.
Not what I meant sorry. I mean you will yield less but from what I've experiences the shorter ones and flowered early seem to give denser buds. Less internode space.
Take it out of the clear plastic container or wrap the whole thing in duct tape. Plants need their roots in darkness, otherwise you won't be pulling anything off her no matter when you put in 12/12.
