Hi Burak, good to hear from you again! I am not sure about the carnivorous plants, but different orchids can withstand different temperatures. Most can dip down for brief periods of time and have little effect, but any real length of time can damage them. We *try* not to let our plants get below 45 F ever. The greenhouse here has its heater set to come on at 59 F. The plants on the edges of the gh and those opposite of the heater obviously get cooler than the ones in the center or in-front / closer-to the heater.

Unless you like it *really* cold in the mornings, I don't expect you would have your temp drop below 50 F in your bedroom, so your orchids should be fine. BUT, like I said, different types of orchids can handle temp drops better than others (some even require a ten degree drop just to bloom).

Congratulations on the new place. I hope you will share photos with us! And again, it is good to see you back online!

Cheers,
BD
