Daytime & Nighttime temps in sunroom
I have a question about safe temperature changes in my sun room and it's affect on my houseplants in there. Because of the nature of the room, on a sunny day, it is often 80 degrees in the sunroom during the day.
However, the lack of insulation means that after dark, the temps drop pretty drastically. I have a space heater out there and I have been maintaining the room at 60 degrees at night.
I'm a little concerned that this 20 degree temperature change could be stressful for the plants. I know the more heat that I use in that room, the drier the air will become, so I have just purchased a humidifier to put near the plants. Thoughts on this? Should I try to increase the temps at night or do you think they will be ok?
