Commodities of Martian Rails: Hydroponics

Martian Rails (2009), the crayon board game manufactured by Mayfair Games about railroading on the Red Planet in which players build tracks and haul freight, has a long list of cool commodities that players can transport to generate revenue for their rail companies. For example:

Hydroponics -- The growing of plants in nutrient solutions under an artificial environment. A way to grow fresh fruits and vegetables on Mars before the soil and atmosphere has been sufficiently terraformed to support them.
