Moisture inside the bottle evaporates from the soil and transpires from the plant leaves. This water vapor condenses on the glass walls and drips back down into the soil, creating a continuous loop of self-watering rain. Bottle Biosphere Guide

If the creator adds too much food, the system collapses. If they add too much light, the system suffocates. It is a delicate dance of inputs and outputs.

A successful bottle biosphere is a meditation on patience. Once sealed, it becomes an artifact of perfect balance—a silent, green world that asks nothing of you except to be left alone in the light. : Nutrient-rich potting soil or native soil containing

Add 2 to 4 inches of substrate. The depth depends on your plants. If you are adding deep-rooted ferns, go deeper. For moss, 1.5 inches is fine. Mist the soil lightly so it is damp (not soaking—like a wrung-out sponge).

Cushion moss, sheet moss, or java moss provide an excellent ground cover.
