The Greenhouse is a tall room with pots full of shrubs, flowers, and 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 2 panels on the oxygen filter used for the Oxygen Depletion sabotage, as well as the Clean O2 Filter task.
