Fungi Farm Mushroom Windowsill Kit - Shiitake

Growing Instructions:
This kit is designed for indoor growing. Choose a clean area away from direct heat sources and draughts. Avoid direct sunlight to prevent overheating. Mushrooms prefer indirect, filtered light.
Please note: Any white-brown bumpy growths indicate early mushroom fruition. These bumps will later become shiitake mushrooms.

Step 1. Prepare the substrate
• Remove the white bag with top soil from the packaging.
• Place the container in a light position at around 15°C (59°F). 
• Avoid direct sunlight to prevent overheating. Mushrooms prefer indirect, filtered light
• Keep the kit covered with the transparent lid until around half of the surface has turned brown.

Step 2. Water immersion
• Immerse the substrate in a bucket of cold water for approximately 24 hours.
• Place a heavy object on top to keep it fully submerged.
Please note: If mushrooms are already growing you may skip the immersion step.

Step 3. Create the right environment
• Remove the substrate from the water and place it into the plastic tray.
• Ensure the surface never dries out.
• Lightly spray at least once a day, keeping it moist but not wet.

Step 4. Harvest
• The harvest period lasts around 1 week.
• Fully grown mushrooms will have caps measuring 4 to 8cm in diameter.

Step 5. Rest and repeat
• After harvesting, allow the kit to rest for at least 15 days.
• Store it somewhere cool and sheltered, such as a garage or garden shed, avoiding dry or hot conditions.
• The next harvest usually arrives after around 10 days.
Please note: Over a period of up to 6 months, you may achieve 5 to 8 harvests.

For more information and guidance check out our Gardening Guides.

Harvesting: Take a mushroom between your fingertips and carefully pull it out with a twist of the hand. Do not pull out without twisting and do not harvest undersized mushrooms. Always water regularly to prevent the ‘cover compost’ from drying out.
