HOW TO CARE FOR YOUR BLACK PEARL OYSTER MUSHROOM KIT?
With proper humidity and consistent care, your kit can yield large, bountiful mushroom flushes:
- Misting: Spray the block with water 2 to 3 times a day to maintain optimal moisture.
- Temperature: Keep the growing area at a steady 21°C and away from direct sunlight.
- Multiple harvests: Under the right conditions, your kit may produce up to three harvest cycles, offering extended enjoyment and delicious mushrooms.
WHAT’S IN THE BOX?
Your kit contains the following:
- Nutrient-enriched, fully colonized block: A substrate of hardwood sawdust, wheat bran, and water, pre-colonized with mycelium. No inoculation is needed; ready for mushroom cultivation.
- Humidity bag: The sawdust block is packed inside a protective humidity bag, which keeps it moist and shields it from contamination.
- Durable box: Compact and sturdy, the box not only holds the kit together but also adds a neat, rustic touch to your indoor setup.
UNPACKING INSTRUCTIONS:
- Open the front flap of the box.
- Cut an “X” into the plastic bag covering the sawdust block.
- Spray the exposed surface with water 2 to 3 times daily and watch your mushrooms grow!
Note: The block may develop a soft, white, mold-like layer on its surface—this is completely normal and indicates healthy, active mycelium, the fungal network that fuels your mushrooms’ growth.
CARE TIPS:
- Maintain humidity: Consistent moisture is essential, but avoid overwatering. The surface of the block should feel slightly damp, not wet, to prevent rot.
- Multiple harvests: Proper care may reward you with multiple flushes over time, offering extended yields.
STORAGE INSTRUCTIONS:
Not ready to start growing right away? You can store the kit:
- At room temperature: Up to 2 weeks.
- In the refrigerator (4-6°C): Up to 1 month.
However, note that prolonged storage may cause mushrooms to begin sprouting inside the filter, which could slightly reduce yields.
This compact yet powerful Black Pearl Oyster Mushroom Kit is ideal for both intermediate and experienced growers, bringing the beauty of gourmet mushroom cultivation to your home.
Each kit is lovingly produced on a small, family-run farm in the scenic Kaunas district of Lithuania.

What’s in the UNGU box?
Inside, you’ll find a pre-colonized substrate block, a humidity bag, and a short growing guide. It’s all packed conveniently and ready for your first harvest.

How to open it properly?
Tear open the box lid where marked. Then, using a clean knife, cut an X-shape into the plastic packaging at the same spot. The block is ready to grow – keep it in the same position as in the box.

Care tips
Mist the block with clean water 2–3 times per day. Avoid direct sunlight, heat sources, and drafts – mushrooms prefer a cool, bright, and humid environment.

Storage tips
If you’re not ready to start growing yet, keep the kit in the fridge (+1 to +5 °C) for up to one month. Important: do not remove it from the bag and store it horizontally.
