Lion's Mane Growing Tips

Everything you need to ensure your Lion's Mane mushrooms are setup to grow perfectly.

Lion's Mane Growing Guide

Quick Setup Check: Keep the paper towel neatly folded, positioned by the front and back holes. However kept away from the box.
Maintain high humidity 80-90% with regular damping of the paper towel and keeping bag raised, but open.

Proper setup is crucial for growing Lion's Mane mushrooms. These mushrooms require specific humidity and air exchange conditions to develop their characteristic cascade of white icicle-like spines.

The humidity bag should be used as a bag rather than a tent, maintaining structure while allowing air flow. Never seal the bag completely.

⚠️ Critical Setup Rule
Keep the product box away from the paper towel - otherwise it will soak up water and compromise humidity levels.

Correct Setup

Proper setup is essential for Lion's Mane cultivation. These mushrooms are particularly sensitive to humidity and air exchange balance.

Essential Setup Steps:

1Keep the paper towel neatly folded, positioned by the front and back holes

2Keep the product box away from the paper towel to prevent water absorption

3Fold the bag over itself for added structure

4Keep the bag 3-5 inches above the height of the box

5Never seal the bag or use it like a tent

Bag Position - Critical for Success:

The humidity bag must maintain the right balance between moisture retention and air exchange:

❌ Incorrect Bag Setup

Signs of Lack of Air Exchange

Warning Sign: Coral-like formations indicate insufficient air exchange. The mushroom needs proper ventilation to form its characteristic cascading teeth.

Coral-Like Formations

If your mushrooms are growing like coral, this is a significant indicator that you are not providing adequate air exchange.

The humidity bag should be used as a bag rather than a tent. The bag should never be sealed completely as Lion's Mane requires fresh air to develop properly.

This coral-like growth pattern occurs when CO2 levels build up too high, preventing the normal tooth development that gives Lion's Mane its distinctive appearance.

⚠️ Air Exchange is Critical - Without proper FAE (fresh air exchange), Lion's Mane will develop abnormal growth patterns and won't produce the desired cascading teeth structure.

The Crop is Turning Yellow?

Some yellowing is normal, especially as the mushroom matures. If you notice this, in most cases it is a sign of maturity and it should be harvested.

Important: Once yellowing begins to occur, this is not something that will reverse back to white. The crop is still choice and edible and will be bright white inside.

Premature Yellowing Causes:

If you are noticing yellowing when the mushroom is much smaller, it is quite likely due to:

Exposure to drafts or air currents
Humidity levels too low
Dry paper towel not maintaining moisture
Box in contact with humidity towels (causing water wicking)

HARVEST TIP: Yellow coloration on mature mushrooms is normal - harvest when the teeth are well-formed and before yellowing becomes extensive.

Troubleshooting Guide

Common Issues and Solutions:

Setup Checklist

Paper towel should be damp but not dripping - mist 2-3 times daily
Bag should create humidity chamber while allowing air exchange within the growing environment
Keep humidity between 80-90% for optimal growth
Avoid direct sunlight but provide indirect light
Harvest when teeth are 1/4 to 1/2 inch long, before yellowing
Box must never touch wet paper towels to prevent wicking
