Fwiw other than a few less commonly kept species, you won't be giving Drosera a sunburn unless you live near the equator or at extreme altitude. They are for the most part true sun lovers that happily take all you can give them and more as long as they don't dry out.
That is good to know..it is just that the seller I got it from always grows them indoors in shade, not in a terrarium just sitting in water. So I just followed same. but it is thriving nicely as you said with full sun by our south facing window. I guess as long as it has moisture below it is okay.
A photo update of my nepenthes..pouch has gone bigger and green, still not ready to open up its lid though. Older pitcher almost died, ooops..I may have been spraying it too much, so I stopped the spraying on the pitchers and has stopped the decay. So I just spray directly on the moss/media. So I think all is well for now.
