Your Blue Oyster Mushroom Harvest Starts Here

There’s something satisfying about cooking with mushrooms you’ve watched grow. The MGS Blue Oyster Mushroom Grow Kit brings that experience into your home, using a colonised growing block housed in a convenient cut-and-grow box.

Blue Oysters develop in clusters of overlapping caps, creating a clear view of mushroom growth as it happens. Their distinctive appearance makes them enjoyable to observe, while their versatility in the kitchen gives you plenty of reasons to look forward to harvest day.

Learn by Growing

This indoor mushroom kit is a practical way to become familiar with cultivation. You begin at the fruiting stage, with the mycelium already established in the substrate, so you can concentrate on understanding moisture, airflow and how a developing cluster changes over time.

There’s no need to prepare grain, mix your own substrate or inoculate the block before starting.

An Everyday Ingredient, Freshly Picked

Blue Oyster mushrooms have a mild, earthy flavour that fits easily into everyday cooking. Their caps can be torn into strips, cooked as smaller pieces or left in generous sections for a more substantial serving.

Try them browned in a pan and piled onto toast, stirred through noodles with ginger and garlic, or added to a risotto near the end of cooking. Their versatility makes this kit appealing if you want a harvest you can use across several favourite recipes.

Why Choose the MGS Blue Oyster Kit?

  • Start with an established, colonised growing block.

  • Watch mushroom clusters emerge through the box opening.

  • Enjoy a compact food-growing project indoors.

  • Explore a versatile gourmet mushroom in your own kitchen.

Is it suitable for a first attempt?

The prepared block removes several cultivation stages, making the kit an accessible starting point for a grower willing to follow the care guidance.

Do I need outdoor space?

No garden is required. What matters is providing a suitable indoor growing environment.

When should I harvest?

Use the kit’s maturity guidance and the appearance of the mushrooms; development can vary with conditions.

Make your next food-growing project a Blue Oyster mushroom grow kit from Mushroom Growing Supplies.

Instructions

  1. Reveal the block: Open the perforated panel on the front of the box.
  2. Create the growing opening: Cut a small X in the exposed plastic bag.
  3. Choose your spot: Place the kit at 15–20°C, with indirect daylight or ambient light and good ventilation.
  4. Keep it humid: Mist the exposed growing area 2–3 times a day using the included bottle. Aim for humidity above 80% around the developing mushrooms.
  5. Pick your mushrooms: The cluster should reach full size in approximately 14 days. Hold it at the base and gently twist to harvest.
