Dusk Caps

Dusk Caps turn a suitable dark, carbon-dioxide space and Slime fertilizer into mushrooms.

WHERE & HOW TO FARM

Where to farm

Use a dark room or suitable dark growing area with 150 g–10 kg Carbon Dioxide, kept between 5 and 35 °C. A compatible Farm Tile or Planter Box can be used for domestic growth.

Dusk Caps are a mushroom crop for rooms that can stay dark and hold Carbon Dioxide. They are unusually sensitive to light: even 1 lux prevents growth. Domestic plants also need Slime fertilizer. Keep temperature and pressure within the species range, then collect mushrooms at maturity for food use. The method is useful when the colony can manage a dark growing area and maintain a Slime supply.

GET STARTED

How to farm

Before you go

  • Dusk Cap seed and a compatible Farm Tile or Planter Box.
  • Carbon Dioxide at 150 g–10 kg pressure.
  • Darkness at the plant; any light prevents growth.
  • Slime fertilizer for domestic growth and temperature of 5–35 °C.
  1. Choose a location that can remain dark, then check for lamps or other light sources that could reach the crop.
  2. Build compatible planting stations and plant Dusk Cap seeds.
  3. Maintain Carbon Dioxide around the plants at a pressure between 150 g and 10 kg.
  4. Keep the room temperature within 5–35 °C and make Slime available for domestic fertilizing errands.
  5. Read plant status after setup and correct any reported light, gas, temperature, or fertilizer issue.
  6. Allow mature plants to be harvested, then move mushrooms to food storage or the colony’s food preparation route.

Farming tips

  • Treat even a faint light source as a growth blocker; inspect the light overlay at the plant rather than relying on the room’s appearance.
  • Check Slime availability before expanding. More domesticated plants increase the ongoing fertilizer demand.

Repeat, collect and use

This crop can produce repeated mushroom harvests while seeds, Slime, darkness, Carbon Dioxide, and suitable temperature remain available. Collect mature mushrooms and keep the growing conditions intact for the next cycle.

Common mistakes

  • Leaving a light source on nearby; remove or block the light until the plant receives no light.
  • Growing in a mixed atmosphere without enough Carbon Dioxide; check the plant’s local gas and pressure.
  • Letting fertilizer delivery lapse; restore Slime access or reduce the number of domestic plants.

When to stop or switch

Continue while mushrooms are useful and the dark room and Slime supply are affordable. Switch crops if keeping the area dark conflicts with colony access or other room uses.
