Mars Modules Edit
The Hydroponics Module is a second tier food facility on Mars.
Yields -24 water and 144 food a day (24 seconds).
Build and send (or recycle the single 1x1 units already landed) four of the Mars Aeroponics Module to make this Hydroponics Module.
Build the Life Support Module first as this can be placed anywhere, and all other modules must attach to a 2x2 already in place.
See the Mars Inc.list for more modules.
