Mushrooms
Coral Tooth
A close relative of Lion's Mane with a branching, coral-like structure and small tooth-like spines along each branch.
Coral Tooth shares Lion’s Mane’s family and its mild, faintly sweet flavour, but grows as a branching, antler-like structure with small spines along each branch rather than one dense mass. It’s a touch more demanding — it notices stale air more quickly, and rewards a slightly more attentive fresh-air routine — which is why it’s marked as moderate rather than beginner difficulty.

Coral Tooth Grow Kit
Lion's Mane's more intricate cousin — a branching, coral-like cluster for a slightly more attentive grower.
Lead time: 2-4 weeks
The growing journey
Colonizing
The block whitens with mycelium — a little slower than its Lion's Mane relative.
Usually days 1–9
Pinning
Small branching knobs appear, the first hint of the coral-like structure to come.
Usually days 9–12
Rapid Growth
Branches lengthen and spines develop along each one — a slower build than Lion's Mane, but a more intricate result.
Usually days 12–16
Harvest
Harvest once spines have extended and are still white to pale cream.
Usually once spines reach around 1cm and are still pale
Second Flush
A second flush is possible, usually smaller and slower than Lion's Mane's.
Usually 10–16 days after harvest

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
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.
Can I grow Lion's Mane indoors without special equipment?
Yes — Lion's Mane is one of the more forgiving species for an indoor windowsill or kitchen counter grow. It needs indirect natural light (not direct sun), room temperature, and a humidity bag or tent, but no grow lights or climate control are required for a first kit.
