HD.....they are simply on LFS and leaf litter from the aquarium. They seem to like it....they are growing well, just not flowering yet. I will keep what you say in mind, though. It will be difficult to plant them on or in anything else except EpiWeb or Hygrolon. No good way to stick a pot into the setup, as you could imagine.
I'll keep the Starcoats in mind....I've heard good things about those bulbs, but it is SO incredibly hard to rationalize a move away from Giesemann's. Way too hard! Lol!
