Will 39 degree outside hurt my flowering plants.
Uhh mind mentioning why the room got to 19f (-7C) ? & for how long lolNo. I've had mine as low as 19-F in the grow room. They can take the cold. They just can't take it for a long period of time.
I am east of the mississippi river and it is supposed to get to 39 degrees for two nights. Thank you for all your help. Shoul I bring them inside for those two nights
