Hi Dennis, I grow several species of Pinguicula and Drosera in my greenhouse. Temps range from 70°s on bright sunny days to low 50°s at night. I don't have them in a terrarium, but do have them sitting in saucers of rain water. They seem to be quite happy this way. They bloom almost constantly but have not been able to set any seed. The biggest problem I have found is that the mice absolutely love them--for lunch--eating (I presume) or possibly just taking entire plants.

(but in a terrarium). And the terrarium will provide the humidity they love. So I think this will be quite successful. I think the tricky part will be removing them in winter and storing them in an appropriately chilly spot. Thanks for the info! If I'm successful with these, I'll try some of the more exotic cultivars on the market. Dennis in Ohio
