This will walk you through the science, the step-by-step construction, troubleshooting, and the profound beauty of creating a world that breathes on its own.

Despite being "self-sustaining," a bottle biosphere requires observation. Finding the Balance (The Monitoring Phase) Using long

Your biosphere will require monitoring over the first two weeks to balance its humidity levels.

Before starting, thoroughly wash the inside of the glass container with hot water (avoid soap, which leaves chemical residues) and let it dry completely. Step 1: Install the Drainage Base
