Since each row will have its own driver, you could easily add an on-off switch to each driver's AC power side, then you could run any combination of 1,2 or 3 rows that works best. For the slight added expense and trouble, you avoid having to take it apart and add a 3rd row if needed. I would definitelly do it that way.
