Beech Mushroom Growkit

The Beech Mushroom Grow Kit is both a flavour-packed addition to your kitchen and an enjoyable growing project at home. Beech mushrooms, also known as Shimeji, are prized for their delicate nutty flavour, firm texture and versatility in a wide range of dishes. This growkit makes it easy for anyone to grow mushrooms at home. No experience required.

The kit comes fully colonised with mycelium and is ready to use straight out of the box. Simply make a small cut in the bag to allow fresh air to reach the mycelium. This signals the start of mushroom formation and kickstarts the Shimeji growing process in a natural, controlled way.

Beech mushrooms thrive in slightly cooler conditions. Place the grow kit in a spot with a temperature between 13°C and 18°C, and provide around 12 hours of indirect light per day to encourage healthy growth. These conditions create the ideal environment for a successful harvest.

Maintaining high humidity is essential, especially during the pinning stage when the first small mushrooms begin to appear. Aim for a humidity level of 90–95% to prevent the substrate from drying out. This step plays a key role in both yield and overall growing success.

If your home environment is on the dry side, place the grow kit in a clear container with a small amount of water at the bottom. Rest the lid slightly ajar so fresh air can circulate. Alternatively, you can loosely cover the kit with a clear plastic bag and mist the inside once a day with a spray bottle. This helps maintain a stable microclimate and ensures a reliable grow with multiple harvests and maximum freshness.
