Yep, although there are some exceptions. Drosera adalae, prolifera, and
shizandra do much better in a terrarium where humidity can be maintained at
high levels. I grow many drosera under fluorescent lights. Sarracenia can
be grown under lights as seedling but generally do better outdoors,
especially the tall-growing varieties, because they need higher light
levels. You might try S. purpurea and S. psittacina under lights because
their leaves are prostrate. Nepenthes will grow outside but I find that in
order to get them to form pitchers, I must grow them in a terrarium where
the humidity is higher. I grow Pinguicula, Drosophyllum, Cephalotus, and
Heliamphora under lights. The cephs are enclosed in plastic to raise the
humidity. No problem with mold so far but I plan to eventually put them in
a terrarium.
