Food is one of the basic resources you will have in your colony, and is essential to the survival of your duplicants. In this build menu you have access to everything related to the cultivation and processing of food. You start the game with the ration box. It works the same way as a storage compactor, but you store everything that has some calorific value in it. Its improved version is the refrigerator. It requires electricity in order to work, and will allow you to protect your food from spoiling.
You will most often have to build a planter box. To build it you will use resources from the Cultivable Soil category, e.g. Dirt. This object will allow you to sow seeds of various harvestable plants. In time you'll gain access to improved versions of Farm Tile and Hyroponic Tile (requiring metal to construct). Both can use various fertilizers to improve the harvest. Hydroponic Tile enables you to hydrate your crops through a system of pipes and improve your harvest even under bad conditions. Aquantic Farm Tile serves primarily to grow plants that need to be planted in water. Apart from that, you can also construct a microbe musher. Here, a duplicate will be working as a cook in order to create simple meals with a combination of different products. You have to select the machine, choose the meals you want to produce and wait for the duplicate to come to the machine. It can be given a specific priority, as can all other tasks. Some meals can pose a risk in the form of a low chance of getting sick, which is a consequence of their low quality. To tackle this issue you can create a cooking station, which allows you to create better dishes and eliminates the risk of illnesses. Not only can it be used to prepare calorific meals from various half-products, but also enables you to increase the quality of the food you serve.
