Greenhouse is a tall room with pots full of shrubs, flowers, plants, and a large oxygen filter with a tree inside. The roof contains several dry plants that sway slowly, and a vent is located behind the filter. The floor is entirely made of some transparent material (possibly glass). There are panels on the left and right of Greenhouse for the Accept Diverted Power and the second stage of the Water Plants tasks, respectively. There are also two panels on the oxygen filter used for the Oxygen Depleted Sabotage, as well as the Clean O2 Filter task.
Impostors can Sabotage Greenhouse, which causes Oxygen Depleted. Players will have 45 seconds to enter a code into two panels, one in Greenhouse and the other in the hallway to the right of Launchpad. The Crewmates will lose if the Sabotage is not resolved in time.
