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.

You might try a sunscreen made just for faces. Clinique has one that I like a lot, and it's not oily at all. As for reapplying, I simply don't do it, but then, I avoid the sun and don't like the look of tans. (To me, they look like what they are - sun damage.)

Oakley I have been using Oil of Olay with 15 spf for years and it works for me, but I thought the 30 spf in Cerave would be better and maybe the moisturizer would be better for my getting older drier skin, nope. Oustide Playing I have been using Bobbie Brown makeup for a long time (now just the eye makeup and blush) but none of the skincare products. I find the BB foundation isn't as good as much cheaper Loreal BB cream. The first time I used it two or three different people at work even commented that I looked great, and very well rested. Maybe I'll try Bobbie Brown and the Loreal and see what I like best. I have to accept the fact that my attempt at suntanning my fair skin as a teen/young adult is catching up with me. And it isn't just my face everything is much drier. I just had a pedicure today and the tech said I was getting calluses and very dry skin on my feet, something I have never experienced. I'm going to see the derm in a few weeks for my yearly skin exam and ask her for her advice.

I had melanoma removed from my cheek in November. I have a fairly big scar, though not that noticeable. To allow the scar to fade, I'm avoiding the sun during prime hours. I prefer mineral sunscreens but most leave a white cast. However, I absolutely love Sun Bum Tinted Sunscreen Face Lotion. It is so so light going on. It is only SPF 30 but since I'm avoiding direct sunlight, it is enough protection. If I can't avoid the sun during prime hours, I like Elta sunscreen. https://www.sunbum.com/products/mineral-spf-30-tinted-sunscreen-face-lotion-1-7oz
