I've seen quite a few ole timers out in OR trim up a rootball, trim the plant down to almost bonsai lookin, put under an easy light and don't feed much. First time I seen it, I jumped up, hollarin, etc, they just laughed at me. Said it was how they keep their moms in smaller spaces. I finally got the nerve to try it and although I went yrs not even hardly trying to touch the rootball, after observing that, I ain't so shy of em anymore. I'll trim a rootbound half gallon pot plant just a little never hitting that main vein, and repot, and most times it takes right off after a day or two. They claimed when they wanted shoots off the moms, they'd feed it a lil more and give a lil more light. Take their cuttings and go on.
