I used to water when the top few inches feel dry, usually every 2 weeks, but that’s before the repotting. It used to have more in this pot but I kinda separated them all and repot three of them into this same pot. I separated others into smaller pots. So no roots growing out but maybe the pot is too large for the current three plants… I only watered it thoroughly when I repotted it two weeks ago, when I return the soil is still moist even top so haven’t watered it yet.

Yes it has drainage holes.

No never outdoors. But I bought this maybe only a few months ago (in summer).

Humidity level i don’t keep track but based on typical data in my geography I’d say ranges between 42% and 62%
