Carolyn defines what, exactly, makes a tomato det or indet, but I suspect there is a complex set of interacting genetics: I suspect most det's have a genetic switch that "shuts them off" after they have set a load of blossoms; idets' do not, generally. But some indets might have at least some capacity to partly "shut off" when they have a lot of fruit...even though the growth points are not terminated by a flower stem.

I've grown Kim and a number of close cousins (Kotlas, Sprint, Stupice, and others): they all seems to exhibit a tendency to slow down or even stop growing late in the season...like a det.
