Total beginner, need a few tips for self-sustaining terrarium build

[ysera]

So once the water leaks back into the soil, it moves through the soil, into the stoney area below? And then it start evaporate once its in the bottom?

How does it evaporate tho? Does it move through the soil again or moves up the side of the bottle of the glass?

It eventually condensates on the glass I see but the middle part of this proccess is a bit unclear.

Also, once it condensates, does it fall back down along the glass?

Is there a specific isopod / springtail breed I should be looking out for?

Also, once lets say the ecosystem is up and running. What are some OUTSIDE factors that can affect the longevity and the overall health situation of the Terrarium? Besides light and heat, I can't think of any.

Thanks again this is so much fun thinking and working my brain on this!
