Petrichor: Cactus, Lake & Fertilizer

Promo tiles unlocked as part of the 2017 Kickstarter Campaign. It comes as two punch boards.

It includes two crop tiles: Cactus ("Opuntia ficus-indica") and The Lake ("Lacus Ludus" - literally 'Game Lake'), together with a token used with the Cactus tile. They can be added to the existing crop tiles to give more variety at game setup.

It also includes fertilizer tokens. These add a new mechanic to the game where fertilised crop tiles yield more return.

The rules are listed on the last page of the rule book of the (kickstarter) base game.
