Hey John,
This is my first attempt with sundews as well, and so far, it's doing pretty good, am seeing some new stems emerging and it seems to have adapted fine to its new environment. It's just bare rooted into the HC, doesn't seem to need any extra moisture, but I mist the tank 2 or 3 times a days anyway, mostly to help the emergent leaves of the Echinodorus adapt.
Will keep you posted on my progress! And thanks for the compliments!
Paul.
