My cephalotus photos...

Thanks, Hongrui. The reddest I have got is slightly less than 1.5". As usual, it is from a plant under T5 lights. Not sure though but for some reasons, many of the pitchers are colouring up lately. I didn't move them closer under the lights like I did with my TC Cephs. This species baffles me.

Btw, Phill says to tell you to fertilise them to get a nicer and darker green. If not, they may be pale green because of the gravel you used.

hmm.. i'm already fertilizing them. at the same strength that i'm using on my neps. i'll probably just monitor them for a while more and maybe will repot all of them if they still don't turn green in 1-2months time.

Same strength as Neps...that's suitable for them. Yup, you might want to repot them. Some and not all, perhaps. 'Cos they are growing well for you afterall. I think even if the gravel is releasing something, the rain would be washing it off after a while.
