    Default When Does Cold Damage Show up?

    So I recently ordered and Orchid, Phalaenopsis "orchid world" (is that correct capitalization? ) and it hit freezing temperatures outside last night and today. It arrived today, so I'm not sure if it was sitting in a cold warehouse, or inside a heated room at the post office.

    It looks fine, but I'm wondering if cold damage will show up later...do y'all think it could still be damaged by the cold and just isn't showing signs yet? Or should it be fine?

    If it looks fine it should be OK. I have no experience with freezing temps but one of the best places to grow phals in my country is in the highlands. altitude 5000 - 6000 feet, where the night temps are in the 50 - 60F. Here in the highland hill stations phals are grown for the cut flower trade.The name of your orchid should be should be written Phalaenopsis (Phal) Orchid World. The grex should be in capital letters since it is a hybrid.

    If you think your phal looks sick, it would help if you upload a picture.

    It looks totally normal, but I was wondering if cold damage shows up quickly on orchids/phals or it shows days/weeks later, because in that case I wouldn't know if I should water it or not?

    Just read the "Orchid naming for dummies" post so I'll try to remember...I'll likely forget though

    I received my 3rd slipper orchid last December (paph fairrianium) and it had been affected (partly) by the cold and it showed by the time I opened the box. One leaf was completely affected. And a couple days later, a second leaf showed the cold damage that was not apparent when I first unboxed the orchid. I cut off half of that leaf. The other part of the leaf survived.

    It's been a couple days and I haven't seen any damage so I'm happy. It got here JUST in time too because it's now in the twenties

    The 20's would have been welcome here the last couple of days. We didn't get above 10 F either Tuesday, Wednesday or Thursday. Today we are supposed to get to 40 before more snow tomorrow.

    I guess I shouldn't complain about how cold I am right now, lol. Whats funny is when I lived in Ohio this was considered tank top weather. Guess Im transforming into a Floridian....rats. Last winter I had some that came in with cold damage, I agree you're probably in the clear if no damage is present but remember that one week is the evaluation time for new arrivals.

    I was just hopping on here to post a question regarding chilly temps and saw this. My orchids are in our sun room which only receives heat that flows from the rest of the house to it. I have placed a radiator in the room to keep them from hopefully getting too cold. The temperatures have been rather cold at night in the 40's which is not normal for us at this time of the year. They are hovering the upper 50's an 60's overnight with the radiator. I know that many phals need a decrease in temperature in order to spike so is this going to be beneficial for them or should I worry because it is too much of a decrease? My other plan was to move them to our warmer room at night and place them back in the sun room during the day but am concerned this much movement would not be good for them especially the paphiopedilum. I have also thought about getting a miniature greenhouse. Any thoughts are welcome.

    Depending on the type of orchids 55-65 is in range of safe nighttime temps. I don't see the problem?
