Here is the gas overlay for the battery boxes. The top room is filled with Hydrogen, and already in-use. The room below is being vacuumed out. When the second room is all vacuum, the pump will be disabled, the insulated tiles between the two rooms will replaced with airflow tiles, and the hydrogen will fill both rooms.
The wheezeworts were planted using Pips. Which is why I'm vacuuming out rooms, instead of digging out vacuumed rooms from the start.
