Not much but worth at least one response!?
Nice job in general
Your darlingtonia looks happy. Any idea as to its day / night temps on that windowsill??
That ceph is gorgeous.. If I were you I'd clip those leaves as close to the rhizome as possible. Then stick the cut ends of the leaves into the LFS around the tank. With some luck, you'd get a bunch of little cephs popping up throughout your tank.
Oh yeah.. hahaha.. I totally forgot I changed my avatar last night. There's one of my tanks. The neps are temporary though. Just some cuttings getting their roots..
You have some really nice plants there, thanks for sharing. Your tank looks amazing. Good work.
