Minimal Temperatures for highland

[guillettoaparicio]

Hi, Monday I’ve received several plants from Andreas Wistuba and I put them in a mini greenhouse (1.2 m x1.2x0.80m) which is in a storage room.
Greenhouse is at 12-13 degrees.
Do highland plants risk anything at that temperature?
I guess if they must be at that temperature at night time, they shouldn’t die at 13 degrees. I also think they won’t probably thrive, but until I find a good heater system I would want to be sure plant will be ok.

Thanks all of you!

I guess they would just grow a bit slower, but not with problems, a constant temperature, when possible is enough, usually around 17-22 for most.
