Diagram of setup for collecting data for C balance curves. Innovations and modifications are shown in blue and denoted by the letters A–D, and sections of the instrumentation expanded for ease of viewing are shown with dashed line connectors. A LI‐6800 (LI‐COR Biosciences) was used as the baseline instrument, including the LI‐6800 large light source (6800‐03) and the upper portion of the bryophyte chamber (6800‐24). We modified the setup to include constant delivery of CO₂ via an attached external cylinder (A), a within‐chamber hydration system including a syringe‐sprayer to deliver water into the closed system (B), a custom 3D‐printed chamber baseplate containing a cylindrical cutout for the silicone plug (C), and a syringe‐based delivery system (D). Diagram is not to scale.
