Everything you need to grow your own Bolle's Bear's mushrooms in as little as 4 weeks.

Yes. The bag arrives pre-sterilised and ready to inoculate, so you do not need a pressure cooker, specialist equipment or previous mushroom-growing experience.

Bolle’s Bear’s Head is straightforward to start, although it needs more patience and humidity than fast-growing oyster mushroom varieties.

Each kit includes a pre-sterilised all-in-one grow bag, a 10ml Bolle’s Bear’s Head liquid culture syringe, sterile needle, alcohol swab and clear step-by-step instructions.

You only need a clean area to inoculate the bag, a suitable place for colonisation and a spray bottle for the fruiting stage. Everything else is included.

Bolle’s Bear’s Head is slower growing than oyster mushrooms. Most growers should allow around 6–10 weeks from inoculation to harvest, depending on temperature and growing conditions.

During colonisation, keep your bag somewhere clean and comfortably warm, ideally around 20–24°C.

Once fully colonised, it fruits best in cool-to-mild, humid conditions. Aim for around 18–22°C with indirect light, regular misting and plenty of fresh air. Cultivation guidance for Hericium americanum commonly recommends fruiting around 18–22°C with high humidity.

Yes, provided you have somewhere suitable for fruiting. A cool bright room away from direct sunlight can work well, as long as you can maintain humidity and provide fresh air.

Keep the bag sealed until you are ready to inoculate. Wipe the injection port with the alcohol swab, inject the included liquid culture, then place the bag somewhere clean and warm while the mycelium grows through the substrate.

The bag is ready once the substrate has turned mostly white with healthy mycelium. At that point, follow the included instructions to cut the fruiting area, move it into cooler humid conditions and begin misting.

Bolle’s Bear’s Head needs high humidity and regular fresh air to develop clean hanging teeth. Dry air can cause the fruiting body to yellow or stop developing, while stale air can lead to denser, less defined growth.

Yes. The first flush is often the largest, but the block can produce additional smaller flushes after resting and rehydrating.

Yields vary depending on temperature, humidity, fresh air and care. Bolle’s Bear’s Head produces light, branching fruit bodies rather than dense clusters, so every grow can look different.

Bolle’s Bear’s Head has a mild, delicate flavour with gentle savoury and earthy notes. Harvested young, it has a soft tender texture and works well sautéed in butter or oil, in pasta dishes, risottos, soups and stir-fries.

Liquid culture gives you a simple way to start growing without needing to prepare grain spawn yourself. The syringe injects directly through the bag’s self-healing injection port, helping keep the process clean and straightforward.
