Sterile technique is the whole game

Learn what 121 °C really does, why 70% alcohol beats 91%, and how contamination actually enters a block.

Temperature, humidity, fresh air — and the CO₂ in between

The three conditions that decide whether a colonised block pins, plus what each failure actually looks like.

The grow cycle

Four stages, every single time

Jars on a shelf or a full fruiting room — the process is identical. Problems at harvest almost always trace back one or two stages.

  1. 1
    Step 1

    Inoculate

    Introduce clean culture to sterile grain or substrate in still air, with alcohol-wiped tools.

  2. 2
    Step 2

    Colonize

    Hold steady warmth and wait. Mycelium spreads white through the block over one to three weeks.

  3. 3
    Step 3

    Fruiting

    Drop the temperature, raise humidity and start fresh air exchange to trigger pinning.

  4. 4
    Step 4

    Harvest

    Cut whole clusters just before caps open, then dry quickly below 55 °C and store airtight.
