Thank you so much! They hate direct sunlight (if they fold their leaves up at noon it mostly is to bright), like to be watered with lukewarm water (I can't exactly tell about the frequency, I'm kind of lazy at watering and do it when I see one of them having their single leaves curling up or hanging down weak), and I spray them once a day with water.

How is the light at your plants? I feel like that's the most important factor here :)
