Why is it that a houseplant living indoors is so sensitive to humidity, water hardness, watering schedule, sunlight… when the same plant has grown outdoors in wild conditions and thrives there?

When you’re growing a plant indoors you often have a *minuscule* quantity of soil compared to what it has access to in the great outdoors. The small soil volume makes it very hard to maintain stable moisture levels, temperature, nutrients and so on because the parameters in your average houseplant pot aren’t being stabilized by the hundreds of cubic feet of soil in the nearby vicinity of something you put in the ground outside.
You’d think weather would impact the soil more, but there’s so much of it that even with a couple weeks of no rain you can normally dig down a few inches to get soil with moisture that the plant roots can easily get at, and similarly with lots of rain (barring extreme events) sloped or drained soils won’t get waterlogged.
In contrast unless you’re using large pots your soil parameters are going to see saw wildly unless you’re very very careful about schedules, and this is hard for a plant to grow and adapt to.
