what can i do with this space?

okay, here's the deal. i want to make a space in my room to grow a few plants. i currently have one grow space (closet) where i already have 1 plant that's in flower.
i have one more baby clone that i'm going to transplant in couple weeks (currently in 1 gallon pot). i want to make this clone a mother plant since it's bubba kush.
only other space in my room other than the closet is a large wall unit.
i figure if the cloning is to be successful, there's plenty of room there to store the clones.
what i was wondering is if i can do anything with the center part of the wall unit with the limited space, and what type set up would be best for this.

ANYWAY SINCE I'M A MORON AND BROKE MY CAMERA, I'M GONNA ATTACH A DRAWING OF THE WALL UNIT.
