How can I split small room?

I am setting up a small room. I have 2 T5 lights one on each wall with a small 2 foot wide area between them. Just enough space to sit and work on one table, turn around in same spot and work on the other table. I would like to be able to light proof between the tables so one can veg as other flowers. However the poly would hang where I want to sit. anyone have any ideas?

Unless you can light-proof the flowering half, and unless you can fit a circulating fan, some form of exhaust and an A/C for both halves, likely not a good idea.
