Everything you need to grow your own Shiitake 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. White Elm Oysters are straightforward to grow, but they do need cooler fruiting conditions than Phoenix or Pink Oysters.

Each kit includes a pre-sterilised all-in-one grow bag, a 10ml White Elm Oyster 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.

Most growers can expect their first harvest in around 4–6 weeks from inoculation, depending on temperature and growing conditions.

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

Once fully colonised, White Elm Oysters need a noticeably cooler fruiting period. Aim for around 10–18°C, with 13–18°C ideal once pins have formed. A cool garage, utility room, porch or unheated spare room can work well. Cooler conditions are an important trigger for reliable pinning with this species

You can, provided you have a cool enough area for fruiting. White Elm Oysters are not the best choice for a consistently warm kitchen or bedroom, especially during summer. A cooler room or sheltered outdoor space is usually more suitable.

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 suitable while the mycelium grows through the substrate.

The bag is ready once the substrate has turned mostly white with healthy White Elm Oyster mycelium. At that point, follow the included instructions to cut the fruiting area, move it somewhere cool with indirect light and begin misting.

This usually means they need more fresh air. Increase airflow around the fruiting area while keeping the surface lightly misted and humid.

Yes. Your first flush is usually the largest, but the block can often produce additional smaller flushes. After harvesting, rehydrate the block and return it to fruiting conditions.

Yields vary depending on temperature, humidity, fresh air and care. Your first flush is usually the largest, with further smaller harvests possible from the same block.

White Elm Oysters have a mild savoury flavour with a firmer, meatier texture than many soft oyster varieties. They are especially good sliced and pan-fried until golden, then added to pasta, stir-fries, risotto, ramen, soups or tacos.

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.
