monkey_Cup, that's a heck of a coincidence, as I stripped down the tank on exactly that same say as you made this post. The Cephalotus did well for a while, but then they slowed down growth. I think there might be a couple of determining factors, one of which is the drainage of the medium. I used just Moorland Gold, with no aggregate, which in retrospect was a mistake. Moorland Gold has finer fibres than normal peat and it compacted rather a lot, creating anaerobic conditions. The other factor is the U. sandersonii which took over the whole tank. If I were to do this again in the future I would definitely add aggregate to the peat, which would probably be grit sand as I don't particularly like perlite.
