@GreenPlant! We're happy you're here and that you're enjoying your plants. Yes, cold Holland is very different from where you were in Portugal!
Humidity is very important, as you've seen. I like the pebble trays filled with water. I do mist, but I'm not sure how much good it really does. I like to fuss with my plants, so misting keeps me happy!
Have fun with the orchids. I am just starting to try them too. I do love their blooms!
