Black Oyster Mushroom Grow Kit — Grow Fresh Gourmet Mushrooms at Home
Growing your own mushrooms has never been easier. The Nature Lion Black Oyster Mushroom Grow Kit lets you harvest fresh, flavourful Pleurotus ostreatus right from your kitchen counter — no garden, no greenhouse, and absolutely no prior experience required. This is one of the most popular mushroom grow kits in Canada for a reason: Black Oysters are hardy, fast-growing, and incredibly rewarding for first-time growers.
Each kit is handcrafted at our CFIA-licensed facility in Brantford, Ontario, using premium Canadian ingredients. From the moment it arrives at your door, you are just days away from your first harvest of fresh gourmet mushrooms.

- Multiple flushes — harvest two or more crops of mushrooms from a single kit
- Fast results — see pins forming within days and harvest within 7–14 days
- Made in Canada — produced in-house at our Brantford, Ontario facility
- Year-round growing — grows indoors in any season at normal room temperature
How to Grow Your Black Oyster Mushrooms
This beginner mushroom kit is designed so that anyone can grow mushrooms at home on the very first try:
- Open — Cut an X-shaped slit in the bag or fold down the top to expose the substrate.
- Mist — Spray the opening with water 2–3 times per day to keep humidity high.
- Harvest — In 7–14 days, your Black Oyster mushrooms will be ready to pick and eat.
After your first harvest, continue misting and the kit will produce additional flushes over the following weeks. Many growers get two to three full harvests from a single kit.
What You’ll Harvest
Black Oyster mushrooms are prized by chefs for their rich, savoury, meaty flavour and velvety texture. They are incredibly versatile in the kitchen — perfect for stir-fries, pasta dishes, soups, risottos, and as a hearty meat substitute. When seared in butter, they develop a deep umami flavour that elevates any meal.
Each flush produces a generous cluster of dark-capped oyster mushrooms that look as impressive as they taste.
Ideal Growing Conditions
- Temperature: 15–21°C (59–70°F)
- Humidity: High — regular misting is all you need
- Light: Indirect natural light or ambient room light
- Location: Kitchen counter, laundry room, basement — anywhere out of direct sunlight
