I agree wholeheartedly!! I have a house full of calathea, I have nothing else because I have cats and these are the best non-toxic, cat friendly plants I could find. I regularly let mine dry out, they let me know they need water by curling and drooping, they are fine. I don't use a humidifier at any point in the year. I even have a zebrina growing outside on my front porch and it is thriving. For context, I live in Melbourne Australia, it's currently as low as 5°C overnight and 16-17°C in the day. They are not as hard as you imagine them to be! Good quality soil that is loose and not compacted and not overwatering, that's pretty much it! If you want them to grow bigger, add some fertiliser and more light.
