People will probably be infuriated I'm posting here (since I've only had this plant for a few months) but...
When I received my Ceph German Giant it acclimated in only a few weeks. I have it in a 5 inch drained pot in a peat/perlite 50:50 mixture with a topping of LSM. It is thriving and making many new pitchers, it has about 6 coming in and one pitcher that is slightly bigger than the biggest one I had when I got it! Huzzah. It has even made a second growth point (it was probably already developing it though when I got it) since I've gotten it, this growth point seems to make smaller pitchers and non carnivorous leaves a lot, but, that's fine.
I also have a humidity dome over it, but, I've tattered it. I poked a few small holes in the top with a tooth pick, tore a giant slice through part of it, and then stabbed more holes in it, then since the Cephalotus is centered I leaned it against the moss a bit and had one end on the pot so there was a large gap, and then there is some area for air to circulate under it, so it's got good air circulation while it has good humidity. I prop one side up on the pot because if I don't then the Summer sun will get it too hot and humid inside, when I prop it up it's only very slightly warmer and still around 80% humidity. Other than this I have a pitchering Nepenthes and a thriving Mexican Butterwort on the windowsill which receives sunlight most of the day and bright shade the rest until sunset.
Basically, I just ignore it, I frequently forget to water it and the soil goes dry, yet this never seems to affect it, I'm paying more attention to it now to keep the soil damp the first day I do it, the next day slightly damp and wait for it to get almost dry and repeat.
. Doing well for me so far...
Now if only I had the coloration...
