Another way to shorten internodes is through nutrition. High PO4 (2 ppm), lower NO3 (5-10 ppm) will help shorten internodes in several plant species.
I believe higher PO4 levels are a cure all for a wide variety of problems we seem to see in our tanks --spot algae, internodal distances, and bringing out red coloration. I could never get my Ludwigia arcuata blood red like in Amano's books until I raised the PO4 levels a tad.
