When I lived on the Mississippi Gulf Coast, I had a great room that had 24' ceilings. I built a tiled in plant area that was 10x10', with water and drain, and 6" side walls enclosed it all in. I had numerous large plants in there and in the center was a Benjamin ficus. It was growing in a large, 1/2 whiskey barrel. That tree finally got about 15' tall. It was never moved and the light only changed some with the season, since the entire south wall was glass. There was never a time that my wife and I were not picking up leaves.
Each to their own, but I'll never have another one. There are many "well-behaved" ficus trees available.
