Well, I was using a 4x4 flood table. So the scrog fit right on top. I haven't scrogged half a rooom of plants in pots. But I am using tomato cages, I wraped twine through, to make a 3d scrog for each potted plant. Though this requires side lighting to work.
Just remeber that you have to reach in there to scrog and tuck an prune an tuck some more. Make the scrog netting tall enough to get under it or low enough to kneel over it. One side should only be 4 ft. That way you can reach the middle. Hope that helps.
