Flora Chamber Oxygen Output

Within the Flora Chamber’s cavernous vaults, the bioluminescent plants release oxygen in delicate mists from their translucent frond tips. This invisible output rises visibly in the dim glow, sustaining the ship’s breathable atmosphere as laborers monitor the plants’ photosynthetic rhythms. The Doctor and Bigon witness this quiet miracle amid the ruined Urbanka hydroponics, where life persists through the very air exhaled by these engineered organisms.
