The Oyster Mushroom grow kit (Pleurotus ostreatus) offers a simple and rewarding way to produce fresh, healthy gourmet mushrooms at home. A classic of home cultivation, valued for its reliability, generous yields, and balanced flavor and texture.

In this new edition, cultivation intertwines with art. The illustrations by Mateo Schmitthenner are not merely an exterior design, but the starting point of a living transformation. As the mushrooms grow, the artwork extends beyond the cardboard and is completed through unique organic forms, making each kit a one-of-a-kind experience.

Renowned for its culinary versatility, the Oyster Mushroom stands out for its meaty texture and mild, slightly earthy flavor. It is an ideal companion for everyday cooking as well as more elaborate recipes, and an excellent plant-based alternative in vegetarian and vegan diets.

Beyond its gastronomic value, this mushroom is appreciated for its nutritional profile: it provides fiber, plant-based protein, B vitamins, and bioactive compounds that contribute to immune support and cardiovascular health.

Why choose this kit?

Easy and rewarding to grow: ideal for beginners, with abundant harvests and no complications.
A living, evolving experience: every cultivation is different; the mycelium and your environment complete the artwork.
Versatile gourmet mushroom: perfect for stir-fries, pasta, rice dishes, risottos, and as a nutritious meat alternative.
An invitation to observe: growth, rhythm, and transformation within the fungal kingdom.

Grow, observe, and let nature — and art — do the rest.

Day 1 – Open the box

Using a cutter or scissors, cut out the marked square on the top of the box.
Through this opening you will see the growing block: a mixture of plant-based substrate (such as sawdust and organic bran) that has been colonized by the mycelium, the vegetative form of our mushrooms.

Day 1 – Make the cut in the bag

Using a clean knife or scissors, make a cross-shaped (X) cut of approximately 3 × 3 cm in the visible plastic covering the substrate (for Hericium: 1.5 × 1.5 cm).

There is no need to remove the plastic or fold back the flaps of the cut. The mushrooms will push through on their own while the substrate remains moist.

Days 1–14 – Water, air, and indirect light

Place the kit in a location with:

Indirect natural or artificial light
Good ventilation, but no direct drafts
Away from radiators or heat sources

Spray clean water directly onto the cut 2–3 times a day, making sure the area stays moist (but not waterlogged).

Days 7–21 – Mushrooms appear

From around day 7 (this may vary slightly), you will notice the first mushroom pins. Spray at least twice a day, more generously.

When you see that oyster mushrooms lose their curved shape or Lion’s Mane develops its characteristic “teeth,” it is the ideal time to harvest. Gently twist and pull the entire cluster to detach it.

And start again…

After a few days of rest following the harvest, you can resume watering and wait for a new flush of mushrooms.

If after the second harvest you notice that the block is drying out or no longer responding, it’s time to give it a hydration boost: remove it from the box and place it overnight in a container of water with the X-shaped cut facing downward.

Then let the excess water drain and place it back in the box. This cycle can be repeated two or three more times, as long as the mycelium remains white, active, and healthy-looking.
