Think of terrariums like the ground of a forest - shaded by the tall trees above but still receiving lots of indirect light.

Again thinking about the environment of a forest - damp and humid. HOWEVER, there needs to be an air of caution with terrariums. It’s better to underwater than over-water. Depending on the size, a terrarium will only need a couple spritz of water, and will only need a top up of water when/if the soil starts to dry out.

Terrariums create their own ecosystem and require very little maintenance - the occasional prune, a spritz of water when required, the correct placement. The water added when I make them gets recycled. Condensation will occur and the water will drip back down into the soil. Note - too much condensation (i.e. never really settling) can mean it is too damp in there. Leaving the lid off for a period of time will help to re-regulate.
