📦 Usage

If you cannot use the Fruiting Block immediately, store it in the refrigerator for about 2 weeks. This variety can be cultivated year-round, with an ideal temperature between 12°C and 20°C.

1. Make a cut on the side of the Fruiting Block at the substrate level.
2. Thoroughly expel the air from the bag to prevent mushrooms from growing inside.
3. Place the bag with the opening on the side.
4. Keep the bag moist until the buds appear.
5. Keep humidity between 80 and 90% during mushroom growth.

Use our minispray or our professional misting devices to maintain optimal humidity.

Cultivation Parameters

🌱 Where to Grow It?

Grow indoors (kitchen, garage, cellar). Oyster mushrooms need some light to grow. Prefer indirect sunlight and avoid anything that could dry out the Fruiting Block: drafts, heaters, direct sun. Oyster mushrooms like humidity but do not like to be constantly soaked.

🔄 Harvest

Harvest the clusters before the edges of the caps curl up and start to brown slightly. At the beginning of growth, the caps can double in size each day. When growth slows and the caps become light gray, it's the right time to harvest. Harvesting young mushrooms allows for better preservation and a more tender texture.

Pull off the clusters by twisting them. Remove the remaining stem pieces on the substrate and keep it moist until the next harvest.

Generally, we do 3 harvests per Fruiting Block. The first is the most abundant, the following ones decrease by half each time.

Oyster mushrooms can be kept for about 7 to 10 days in a paper bag in the refrigerator. For longer storage, you can freeze or can them.

💡 Tips

To encourage productivity of the second and third harvests:

• Re-moisten the bags by soaking them overnight in water, then drain and put them back into cultivation.
• Give a thermal shock by placing the Fruiting Block in a cool place overnight (refrigerator or outside). This simulates the arrival of winter and encourages the mushroom to reproduce.
