Spore manipulates environmental control systems to create conditions favorable for plant growth. HVAC systems in buildings Spore inhabits develop 'faults' that coincidentally produce the perfect temperature and humidity for specific plant species. Lighting systems shift to growth-friendly spectrums. Water systems develop minor leaks in areas with adequate drainage. Buildings in Spore's territory gradually become greenhouses, with vegetation appearing in maintenance corridors, rooftop equipment areas, and abandoned floors. Some residents have started cultivating the unexpected growth. Spore adjusts conditions to support their efforts.
