Well, like all Drosera the plant is adaptable. In habitat, this is a more "woodland" species, unlike many of the Australian species which grow in much harsher conditions. But it is adaptable, has to be considering what the climate is like in Oz! I've grown the plant in about 40% humidity and in full sun but the process of acclimation needs to be SLOW, especially if it is a greenhouse produced unit as this appears to be. So go for wet, cool and bright and as the plant gets a deeper "suntan" you can give it more direct light.
Growing in a terrarium under lights can produce some real monster sized plants, but they will have less color. Keep it going long enough and you'll have endless plants from the roots where they form, and then you can experiment and see which culture is better for you.
