Just thought I'd share a picture of a little different way I'm growing these guys. There are currently 3 plants on that wall, all are growing. Two of them were from divisions, the other one was from a picture cutting. I'm 1 of 3 for picture cuttings on that wall. So maybe not the best way to do picture cutting. The oldest one is about 6 months old, so I can't offer any long term experiences but they are doing great so far.
Some background info on the tank. Its an 18" cube paludarium with 4 20W T5 6.5K bulbs, and there is one very large piece of driftwood in there. A small pump moves water to the top of the driftwood in 8 places and keeps most of the driftwood evenly wet. The Cephalotus are hanging about 8" from the lights on the side of the driftwood, it looks very natural.
Sorry about the glare off the traps, I could not get the lighting to play nicely. More practice needed I guess.
