That's limited but, you can do something really cool with this set up. I just hope you know how to deal with stretch ! Girl scoot cookie from fast buds fits perfectly. Some says it's a tall girl, but not really if you block the stretch.
You can have a tall girl in this room if you make her grow in circle. Not recommended if it's your first grow.
Be really careful with your choice. think about the distance between your apex and the light, the size of your container, etc... With this set up it would be more interesting to grow few small girls, than 1 big. By eye, I would say you can grow 4 tiny plants. But i would recommend 2 tiny. Also be sure your light is not too powerful for your growth.
Also, if i had this type of set up i would add some mylar on the walls to help the light spreading through the leaves.
Keep on rocking!
