Acquiring wheat in Solarpunk is a vital step for players looking to advance beyond the game's initial stages. This staple crop is often listed as a research requirement early on, but it is not available on the starting islands and cannot be obtained through merchant trades.
Players must first establish a sufficient production line to afford an airship upgrade. Once this upgrade is complete, new island clusters become accessible, offering access to wheat and other necessary resources. Wheat grows on larger island clusters located to the east and west of the merchant ship. However, these locations are beyond the reach of the starter airship.
To reach the wheat-producing islands, players must upgrade their airship. This process involves trading a significant amount of materials to the merchant, including watermelons, cotton, a large quantity of beeswax, and processed copper. After acquiring the airship upgrade component and returning to the dock, players can interact with a panel to perform the upgrade without further material costs.
The island cluster east of the merchant ship contains wheat and other useful plants, alongside a water supply which could be beneficial for base relocation. The island cluster west of the merchant ship is particularly valuable, featuring wheat, several quartz nodes, and a quartz vein on the farthest western island. Players are advised to bring a drill to this location for efficient quartz extraction, as it is needed to create silicon for various projects.
Both newly accessible islands contain supply chests with useful items that players should loot. Upon gathering approximately eight wheat seeds and eight clusters of wheat, players can return to their base. Planting these seeds will allow for the establishment of a wheat farm. Unlocking the next research tier and basic animal husbandry with the harvested wheat will further enable progression, including the utilization of resources for animal care.
Using sprinklers can ensure wheat crops are reliably watered, aiding in consistent harvests and continued progression in the game.
