Hmm, people seem to be saying Cephs can grow warm, how many of you who are growing them in warm conditions have been doing so for over a year? I ask because I thought they needed the seasonal variation (temp/light) change to stay healthy. I grew my first one for a year or two in my old HL chamber, it became a very nice clump and then it just sort of petered out. Years later I've got another and put it in low light hours (but under relatively bright lights which grow/flower my succulents) and cool day/night temps ("winter") and it's really just poking along, it's been working on the same two new pitchers for a couple weeks now and they're still pretty small.
Perhaps I should put it into warm LL conditions with my N. amp "Harlequin' to kick start it?
