Mushroom growing kit: instructions and success tips

A mushroom at home? Yes, and very simply

Mushroom growing kits are the easiest way to produce fresh, tasty, and organic oyster mushrooms at home, without experience or complicated equipment. Here is the complete guide to get started, with practical advice and cultivation tips.

1. What does a mushroom kit contain?

• A substrate block already inoculated with mycelium (often based on straw, sawdust, coffee grounds…)
• A perforated packaging or a growing bag.

2. Where to place the kit?

• Ideal temperature: 15 to 22 °C (avoid direct heat sources).
• Humidity: naturally humid room (kitchen, bathroom, cellar…), or create a mini-greenhouse.
• Light: indirect, no direct sunlight.
• Ventilation: essential to avoid mold.

3. How to start fruiting?

• Step 1: open the kit window or cut a square in the bag according to instructions.
• Step 2: spray 2 to 3 times a day with non-calcareous water (filtered or rainwater).
• Step 3: maintain ambient humidity with a pierced transparent plastic bag as a “soft greenhouse” if necessary.

🌱 Growth time

In a few days, “pins” (mini mushrooms) appear. Harvest usually takes place 7 to 15 days after activation.

4. Harvest and restart

• Harvest mushrooms by gently pulling at the base, without cutting.
• Let the kit rest a few days without watering → mycelium rest.
• Resume spraying → a new flush may appear (up to 2 to 4 harvests).

5. Bonus tips

• Keep harvested mushrooms cool (3 to 5 days), or dry them.
• Recycle the substrate in compost or garden after the last flush.
• Add coffee grounds

Conclusion

A mushroom growing kit is an opportunity to discover the magic of mycelium… at home. Easy, fun, educational, delicious: a perfect activity for young and old, all year round.
