Production of mushrooms for Farming 19, or rather cultivation on a plantation. A business is purchased for a price of 60,000 rubles, and then it needs to be watered and fertilized with manure.
Such mushrooms still grow near Chernobyl, but no one has seen them yet. In any case, they require a script from the Global Company!
A Shroom Factory mod has been made in the FS19 farming game for growing large mushrooms.
