I live in an apt building, and the side that I'm on is in the shade in the morning, and full sun after about 10am.
The mornings here recently have been pretty chilly, like 15*C, and I'm wondering if this is bad for the sundews, flytraps, and 2 small pitcher plants I'm growing out there, and if so what can I do about it?
The water in the planter box is pretty cold overnight and only gets to about 17*C during the day(beige planter box, insulating foam on top that the pots sit in) but the soil the sundews are in warms up to about 20*C.
are the cold mornings a problem?

these plants are tougher then you think, highland neps like drops. if your really worried you can bring them in at night. Sib

not so much worried as I was just not sure. The balcony actually starts getting sun at about 8am.

I think the temperate CP's really like wide temperature swings: from cold nights (above 0C) to hot sunny afternoons.

in their natural environment what would the temp range of the soil be though?
it may get to 10C at night sometimes, but in a big bog would the ground temp get that cool?

I was reading about live sphagnum moss and bogs in nature and from what I have read, the sphagnum moss tend to grow up around sundews and VFT and some other CP's. The sphagnum moss because it is so acidic depending on the species of sphagnum mosses in the bog or fen, the acidity actually resists freezing or decreases the temp at which the moss and ground cover freezes at. This means that even though the temperature outside in the wind may be 21F or -6 C, the ground temp around the bog can be 0C or warmer and also shelters the Cp's from any freezing temps. It is sort of like having an insulating blanket covering everything, so only the upper most leaves or exposed parts of the plant get damage from frost. I unfortunately, live in a VERY cold town in montana where temps get to -40F or -40C which is unsuitable to overwintering any cp's outside, so I have to use the fridge method to overwinter my plants, but I will only let the plants get down to 36F or 2.5C since they do not need the temps as much as the difference in hours of exposure to light between winter and summer.

Just as a little side-note. It's perfectly fine to start new threads for things like this so old posts don't get brought back up. Really cool info too.

If you have an attached outbuilding or cold cellar you could possibly use those for dormancy. Our garage is unheated and outside the house but attached by one small wall-it never goes below ~0C even if it's -20C outside.
I'm not sure what the ground temperatures would be under a good mulch and snowcover when it hits -40. Might be surprisingly close to 0C, though. You could always make a test plot and use a outdoor logging thermometer to check. I think a few of our northern members do the dew outside in the winter and our winters are nothing to laugh at.
