Interesting, this hasn't been my experience with it. I have had mine for better part of a year and only a few leaves have come out green. Aside from that, I do not prune it. I have propogated 5 pups from it so far, all are orange and one is going crazy with pups now and i'm going to be propagating another 5 or so off of it. My display tank with the original mother is around 100-150umols and my buce tank with the younger mother plant has not yet been tested with a PAR meter, but I doubt the PAR is over 80umols at the substrate.
Edited to add that I sourced mine from another hobbyist friend and his are from the Aquasabi TC.
