A temperature swing like that in nature, about 20 degrees, is normal most places, most nights, and often a bigger gap than that. It's hard to say if your specific plants would like the same conditions as anyone else might describe though. The room where all of my plants spent the past few winters gets down to around 55 if it's really cold at night. Might get to 65 in the daytime. The last winter I was in OH, my plants lived in an unheated room that would get down to about 45 but had windows on 2 sides and was sunny and much warmer during the day. Wow we saved a lot of money when we realized what a sieve that room was and closed the vent and the door. MIL just staples plastic over the screen of her back porch and uses no additional heat except a light bulb if she thinks it's necessary at night. She has about 50 different plants but more actual pots, many identical to mine as we've traded about everything possible that either wanted. Last winter she had several Coleus stay alive in there, so we can be sure it didn't get to a frost in there although it dipped below that point outside many times. My neighbor who has plants that are older than I am uses an unheated shed that's a very dark color and does have some insulation and windows, so I'm sure warm and sunny in there by afternoon. She said she turns on a space heater on its' lowest setting on nights below 25. If you have some kind of risers or stands for any plants sitting directly on the floor, even a couple inches that would prevent the pots from making contact with the ground, which is usually much colder than the ambient room temperature, the plants might appreciate that. A room that's 68 might read 52 if you lay a thermometer right on the floor. You plants might get a lot of benefit running a little fan for a few minutes a couple times a day, or as much as you feel reasonable. In your room that doesn't get dry air from central heat/furnace, and having multiple plants, the humidity would not be as much of a concern for your room as one being kept 30-40-50- degrees warmer inside than out with a central system. It may be more humid in there than you think. It's definitely humid in here, condensation on the windows in the morning, we don't run the central heat.

A rare plant so likely few experienced folks. You might check over on the Bamboo Forum here. I bet some of the folks there could better advise you. Dave Here is a link that might be useful: Bamboo Forum

Missherry, when you say they pupate before cold weather sets in, do you mean they usually have pupated by this time of year, in your area? It still isn't cold here, consistently anyway, anywhere from mid 90's to mid 60's from day to day, lol. My cats do seem to have sped up quite a bit this week, I think they are all last instars except for two, and my new little ones of course. Just wondering if it is kind of late in the year for them to still be eating and growing, I wish they would hurry up, lol!!

And I still have some Brandy Boys that I promised you Brandy. Along with some seed promised Theresa. I just sent her an email and she has all of my contact info. I am heading back to Wilmington tomorrow ( Tuesday at the latest) and also have to go through New Bern one day this week ( maybe that passes closer by?). I am taking some to drop off to a friend in Columbia, SC and can haul around some for you if you still want them .. or I can try mailing them if you still want them.
