I think your enclosed growing chamber concept is very interesting. You probably are already aware to look out for overheating and to provide some additional ventilation if necessary. I'm amazed at the growth you get with just the one CF light.
I'm not yet confident enough of my limited success with Cephalotus follicularis, that I would give any advice on growing it. I see that many of your other CP, especially Drosera indica /D. hartmeyerorum seem to be growing well.
