they can be a bit picky with light too – light but not direct sunlight. And as marty says, well away from a draft …. which is why you need to be careful abotu where you buy them from! Cut flowers and pot plants by the drafty supermarket door anyone?? <<< just dont buy them, they will not last!
If you’ve got a Phalaenopsis orchid (most common one sold in garden cnetres, supermarkets etc). It’s important not to let night time temperatures drop below 16 degrees so be careful now in the winter months
