Hi everyone! My dad's house is empty, and I have turned the ac/heat off. I noticed today that the temp in the house is 59 F. As I am trying to prevent a high utility bill, can you please tell me how low I can let the temperature in the house get, and not hurt the plants? He has African violets, arrow plants, schefflera, Christmas cactus, Peace lilies, and a vine with heart shaped leaves that may be a Philodendron. Also, with the temperature low, should I move the plants out of and off of the window sill and window shelf? Some of the leaves of the African violets touch the window. I am in West Tennessee, and the outside temp gets below freezing during the winter. For the plants that are not near window light, will a regular ceiling light be enough for them? Thank you all so very much!
