Mushroom

The mushroom turns the rules of farming upside down. According to the game data it needs no light but 1,100 s of darkness per day, and it takes damage after only 120 s of light. It differs in gas too: it breathes in oxygen and breathes out carbon dioxide, like a human.

That has practical consequences. Mushrooms belong in their own dark room or in trays without a lamp – never under a Grow Light that is running for the other plants. And without oxygen it suffocates faster than other plants: after 300 s instead of 3,600 s.

It still combines well: a mushroom room produces exactly the carbon dioxide the plants in the light room need, and vice versa. Two rooms connected by ventilation complement each other.

It is ripe after 3,601 s, carries seeds from 4,801 s and gives up to three per harvest. Raw it has 10 nutrition with a slight mood penalty (−0.25), cooked as Cooked Mushroom 40. Five mushrooms, 1 steel and 1 oil make a can with 120 nutrition in the packaging machine. Temperature and pressure: ideal 20 to 30 °C and 50 to 100 kPa.
