YIKES !!!!!! Based on plant height alone you should have been flowering already, that plant is going to overwhelm your space.
As for the above post mentioning "LST", you need to read up on processes to keep your plants short and bushy. Those processes would include: LST, SCROG, Bondage ( without the domination ) 12/12 from seed, etc etc etc.
Make your next grow worthy of your space.
