I am in a slight panic about nighttime temps for orchids. We recently heated our back sunroom and I have most of my orchids there. Last night, (and typical lately), the temp outdoors was in the lower twenties with winds. My sunroom is set at 62, but along the outside windows the temp is about 57 to 59 degrees. I made sure any drafts were sealed from the beginning. It can be two or three days without sunshine. I guess what I need to know is if that 57 to 59 degrees during the night time will do any harm over a period of time and if the lack of sunshine during the winter will alter things in a damaging way. I always have light, however no strong sunshine every day. My orchids are phals, catts, dend, milt, brass, angraecum, ascocendas, restrepias, pleurothllis, and too many more to name, but I have quite a variety.
Everything looks okay so far, but I really don't want to lose any of them.
Do any of you see a long term potential problem? Everything seems to be in spike or buds, so I know the cooler temps have been beneficial in that regards. I desparately need feedback on whether to pull them back into the house or leave them be. Thanks so much for any help!
