Fresh Air and Mushroom Shape
Why oyster mushrooms in particular grow long and pale without enough fresh air, and how much airflow is actually enough.
Is the white fuzz on my grow kit mycelium or mould?
Reading White Fuzz
Almost every new grower asks the same question in the first week: is this white fuzz the mushroom, or a mould? Usually, it's mycelium — here's how to tell.
Frequently asked
Why are my mushroom stems long and pale instead of short and broad?
This is almost always a fresh-air issue, especially common with oyster mushrooms — not enough air exchange causes long, pale, "leggy" stems and small, curled caps. Fanning the opening a few times a day usually corrects the shape of the next flush. See the full guide on fresh air and shape for more detail.
Is white fuzz on my grow kit normal?
Yes, in almost all cases. White, cottony growth in the first two weeks is mycelium — the mushroom itself — rather than mould. Genuine mould usually shows colour (green, black, pink) rather than staying white. See the full guide on reading white fuzz for the specific signs to watch for.
