Dear Bill Weaver,
thanks for responding!

If the light intensity is too low it will certainly help.
When doing this, it will be important to use the right light source, since it is known that a light source with a high portion of dark red will support elongation of internodes again. Contrary a high blue portion will support compact growth.
However, when for instance one of the big Amorphs gets taller and when light conditions are near to the optimum, I would expect that it cannot be kept short even by giving it extra blue light. One again has to think of other means and here I would come back to growth retardants.
Thanks again and good growing,
