You close the door and leave the mushroom to its work. But there are things to watch for, and days on which you should look.
From every grain of spawn the mycelium emerges and spreads outward in a circle. You see this as white patches that slowly grow until they run into one another.
During this time the mushroom needs no light. It has no chlorophyll — sunlight is of no use to it. What it needs is warmth, quiet, and a little air.
| Condition | General rule | Why |
|---|---|---|
| Light | Dark, or very dim | Not needed; light is a signal to fruit, and it is too early for that. |
| Air | A little, but not sealed | Mycelium breathes. But strong airflow dries it out. |
| Handling | Leave it alone | Repeated handling breaks newly grown mycelium. |
| Temperature | Steady, not fluctuating | Sudden changes slow colonisation. |
The type and size of the house, materials, cost, how many bags per square metre, the target temperature and humidity, and how it is achieved without machinery.
How far the white should have travelled by day 7, day 14 and day 21.
