They aren't micro tomatoes either, but in researching sun dwarf, I came across this very interesting piece by Darren Abbey:
http://the-biologist-is-in.blogspot....-tomatoes.html wherein he says the following: "The dwarf plants are distinguishable very early because the leaves remain splayed (yellow 'D's at right), while in normal plants they fold upwards at night (red 'N's at right)".
That is incredibly helpful to me
